The Mozilla Foundation released the second major security update this week for their flagship browser Firefox. The fix patches a serious flaw in the way Firefox handles animated GIF image files. Firefox browsers infected by malicious code could experience a buffer overflow, temporarily locking up or “freezing” a user’s computer, or even executing arbitrary code which could take over a user’s computer.

The flaw was discovered and reported by Internet Security Systems, Inc. The upgrade was the second major security fix in less than a month for the browser, which has grown in popularity to ten percent of the browser market in the United States.

Although there were no known exploits of the bug, Chris Hoffman, director of engineering at Mozilla, told reporters, “[because] Mozilla is committed to delivering the most secure product possible, we decided to quickly issue an update to patch the bug.”

The Mozilla Foundation did not offer any details about the issue of vulnerability, but a second major security overhaul in such a short time underscores challenges faced by the nonprofit foundation as it goes head-to-head with the market leading Internet Explorer browser by Microsoft.

The new release, Firefox version 1.0.2, “illustrates the dedication of the strong community of developers working on the product,” according to Hoffman. “…we’re able to turn around patches much faster than a traditional corporation,” he added.

Users can download the update at no charge, and can find additional information at the Mozilla website.

On Tuesday, US-based software company Red Hat announced their plans to shift their focus away from CentOS in favour of CentOS Stream.

In the blog post Chris Wright, the Chief Technological Officer of Red Hat said Red Hat had informed the CentOS governing board that Red Hat was “shifting our investment fully from CentOS Linux to CentOS Stream”. At least five of the nine CentOS Governing Board listed on the project are Red Hat employees.

Started in 2004, CentOS has been a free-of-cost free/libre open source software which provided binary-code compatibility with Red Hat Enterprise Linux (RHEL) — Red Hat’s GNU General Public Licensed paid operating system. CentOS was absorbed into Red Hat in 2014, with Red Hat gaining the trademark rights of “CentOS”.

Red Hat also sponsors the Fedora operating system. Red Hat even gives the software engineering interns laptops with Fedora on it. Till now, software development took place on Fedora, which was later adopted in RHEL, which the Red Hat maintained and provided support for, for those customers who had RHEL subscription. CentOS would then follow RHEL to provide the same features free of cost, but without the support.

Stream was announced in September 2019, just two months after Red Hat was acquired by IBM. CentOS Stream’s development cycle had new features added to it before the features became a part of RHEL. Stream receives more frequent updates, however, it does not follow RHEL’s release cycle.

With CentOS Stream, developments from the community and the Red Hat emplyees would take place beforehand on both Fedora, and Stream as a rolling release, before those features are absorbed into RHEL. CentOS followed the release cycle of RHEL and therefore it was a stable distribution. Features available in CentOS were tried and tested by Fedora, and then RHEL maintainers. Stream, on the other hand, has features added to it before those features become a part of RHEL. That implies Stream would be ahead of RHEL’s development, containing new features which are not yet tried and tested by RHEL developers, and not be binary code-compatible with RHEL.

Writing “The future of CentOS Linux is CentOS Stream”, Wright further wrote in the announcement, CentOS Stream “provides a platform for rapid innovation at the community level but with a stable enough base to understand production dynamics.” Wright also said, “CentOS Stream isn’t a replacement for CentOS Linux; rather, it’s a natural, inevitable next step intended to fulfill the project’s goal of furthering enterprise Linux innovation.”

Since the announcement was made, many people expressed their anger on Internet Relay Chat (IRC), Reddit and CentOS project’s mailing list. CentOS 8’s End of Life (EOL) has been moved up from May 2029 to December 31, 2021, while CentOS 7 is expected to receive maintenance updates through June 2024, outliving CentOS 8.

Gregory Kurtzer, who had started the CentOS project, announced a new operating system, Rocky Linux. Rocky Linux describes itself as “a community enterprise Operating System designed to be 100% bug-for-bug compatible with Enterprise Linux”. The project said “Rocky Linux aims to function as a downstream build as CentOS had done previously, building releases after they have been added to the upstream vendor, not before.” The project maintainers have not decided a date for when the operating system will be released.

Kurtzer explained the reason to call the OS as Rocky Linux: “Thinking back to early CentOS days… My cofounder was Rocky McGaugh. He is no longer with us, so as a H/T [hat tip] to him, who never got to see the success that CentOS came to be, I introduce to you…Rocky Linux”.

Wikinews reached out to the members of the CentOS project, Pablo Greco and Rich Bowen, to discuss this move, its implications as well as the future of CentOS. Greco is a maintainer of armhfp (32-bit processors) and is a part of the CentOS’ quality assurance team. Bowen — who unlike Greco, works for Red Hat — is the community manager of the CentOS project.

Bruce, Canberra — This past week, an overstocked Australian Opals, the women’s national basketball team, prepared for the 2012 Olympic Games in London with a weeklong training camp at the Australian Institute of Sport (AIS) to be used to help narrow the nineteen member Opals squad down to the twelve that go to the Games, and provide players who rarely play together an extended period of time to play together in order to improve on court dynamics.

Camp started on Sunday, with players arriving from hometowns around Australia including Cairns, MacKay, Gladstone, Brisbane, Adelaide, and Melbourne.

The defending champions, the United States women’s national basketball team, are perceived as the Australian Opals’ main competitors. In the last three Olympic Games the Opals got silver medals. In each of these cases the United States got first place. Coach Carrie Graf said “thinking about the US too soon in inappropriate”, “Our focus is first and foremost, game by game winning our pool”. Amongst the Australian Opals’ competitors in the pool are Brazil, Russia, and Great Britain. Carrie Graf said Great Britain “will put up a fight on home turf” but there is a “world class [AIS] facility” and “world class medical support staff” supporting the team.

Australian Opal player Penny Taylor recently suffered injury from a torn anterior cruciate ligament, meaning she cannot play Olympics this year. In regards to the situation player Lauren Jackson, who is going into her fourth Olympics, said “you would never wish that upon anybody.” She says as a team they have to “move on, move through that” and “come together” to pick up their offence and defense. Despite the loss of one of their key players she says “we definitely have the talent there” and the team is all “on the same page.” She feels “pretty confident” and speaks of “very exciting” times ahead. Jenna O’Hea is going into her first Olympics with the team. She is still “pinching” herself and says she is taking it “day by day”.

A typical day at the camp might start with a 7.00am – 8.30am breakfast at the AIS Dining hall, before one and a half or two hours of court, gym, or swimming training. The middle of each day might consist of media meetings, medical checks, team meetings, and time to practise shooting. Around 12.00pm, the players meet to eat lunch and recover from the morning. The afternoon typically consists of more training, and some scrimmage games. Players usually finish around 7.00pm for dinner, and perhaps a massage.

The nineteen players in attendance this week at training camp were Suzy Batkovic, Abby Bishop, Elizabeth Cambage, Rohanee Cox, Cayla Francis, Kristi Harrower, Laura Hodges, Natalie Hurst, Lauren Jackson, Rachel Jarry, Kathleen MacLeod, Jenna O’Hea, Samantha Richards, Jennifer Screen, Belinda Snell, Marianna Tolo, Kristen Veal, Carly Wilson, and Hanna Zavecz. Basketball Australia has named fifteen players that are to attend the second phase of the camp: Suzy Batkovic, Abby Bishop, Elizabeth Cambage, Kristi Harrower, Laura Hodges, Lauren Jackson, Rachel Jarry, Kathleen MacLeod, Jenna O’Hea, Erin Phillips, Samantha Richards, Jennifer Screen, Belinda Snell, Marianna Tolo, and Hanna Zavecz.

A team of eight transplant surgeons in Cleveland Clinic in Ohio, USA, led by reconstructive surgeon Dr. Maria Siemionow, age 58, have successfully performed the first almost total face transplant in the US, and the fourth globally, on a woman so horribly disfigured due to trauma, that cost her an eye. Two weeks ago Dr. Siemionow, in a 23-hour marathon surgery, replaced 80 percent of her face, by transplanting or grafting bone, nerve, blood vessels, muscles and skin harvested from a female donor’s cadaver.

The Clinic surgeons, in Wednesday’s news conference, described the details of the transplant but upon request, the team did not publish her name, age and cause of injury nor the donor’s identity. The patient’s family desired the reason for her transplant to remain confidential. The Los Angeles Times reported that the patient “had no upper jaw, nose, cheeks or lower eyelids and was unable to eat, talk, smile, smell or breathe on her own.” The clinic’s dermatology and plastic surgery chair, Francis Papay, described the nine hours phase of the procedure: “We transferred the skin, all the facial muscles in the upper face and mid-face, the upper lip, all of the nose, most of the sinuses around the nose, the upper jaw including the teeth, the facial nerve.” Thereafter, another team spent three hours sewing the woman’s blood vessels to that of the donor’s face to restore blood circulation, making the graft a success.

The New York Times reported that “three partial face transplants have been performed since 2005, two in France and one in China, all using facial tissue from a dead donor with permission from their families.” “Only the forehead, upper eyelids, lower lip, lower teeth and jaw are hers, the rest of her face comes from a cadaver; she could not eat on her own or breathe without a hole in her windpipe. About 77 square inches of tissue were transplanted from the donor,” it further described the details of the medical marvel. The patient, however, must take lifetime immunosuppressive drugs, also called antirejection drugs, which do not guarantee success. The transplant team said that in case of failure, it would replace the part with a skin graft taken from her own body.

Dr. Bohdan Pomahac, a Brigham and Women’s Hospital surgeon praised the recent medical development. “There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

Leading bioethicist Arthur Caplan of the University of Pennsylvania withheld judgment on the Cleveland transplant amid grave concerns on the post-operation results. “The biggest ethical problem is dealing with failure — if your face rejects. It would be a living hell. If your face is falling off and you can’t eat and you can’t breathe and you’re suffering in a terrible manner that can’t be reversed, you need to put on the table assistance in dying. There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

Dr Alex Clarke, of the Royal Free Hospital had praised the Clinic for its contribution to medicine. “It is a real step forward for people who have severe disfigurement and this operation has been done by a team who have really prepared and worked towards this for a number of years. These transplants have proven that the technical difficulties can be overcome and psychologically the patients are doing well. They have all have reacted positively and have begun to do things they were not able to before. All the things people thought were barriers to this kind of operations have been overcome,” she said.

The first partial face transplant surgery on a living human was performed on Isabelle Dinoire on November 27 2005, when she was 38, by Professor Bernard Devauchelle, assisted by Professor Jean-Michel Dubernard in Amiens, France. Her Labrador dog mauled her in May 2005. A triangle of face tissue including the nose and mouth was taken from a brain-dead female donor and grafted onto the patient. Scientists elsewhere have performed scalp and ear transplants. However, the claim is the first for a mouth and nose transplant. Experts say the mouth and nose are the most difficult parts of the face to transplant.

In 2004, the same Cleveland Clinic, became the first institution to approve this surgery and test it on cadavers. In October 2006, surgeon Peter Butler at London‘s Royal Free Hospital in the UK was given permission by the NHS ethics board to carry out a full face transplant. His team will select four adult patients (children cannot be selected due to concerns over consent), with operations being carried out at six month intervals. In March 2008, the treatment of 30-year-old neurofibromatosis victim Pascal Coler of France ended after having received what his doctors call the worlds first successful full face transplant.

Ethical concerns, psychological impact, problems relating to immunosuppression and consequences of technical failure have prevented teams from performing face transplant operations in the past, even though it has been technically possible to carry out such procedures for years.

Mr Iain Hutchison, of Barts and the London Hospital, warned of several problems with face transplants, such as blood vessels in the donated tissue clotting and immunosuppressants failing or increasing the patient’s risk of cancer. He also pointed out ethical issues with the fact that the procedure requires a “beating heart donor”. The transplant is carried out while the donor is brain dead, but still alive by use of a ventilator.

According to Stephen Wigmore, chair of British Transplantation Society’s ethics committee, it is unknown to what extent facial expressions will function in the long term. He said that it is not certain whether a patient could be left worse off in the case of a face transplant failing.

Mr Michael Earley, a member of the Royal College of Surgeon‘s facial transplantation working party, commented that if successful, the transplant would be “a major breakthrough in facial reconstruction” and “a major step forward for the facially disfigured.”

In Wednesday’s conference, Siemionow said “we know that there are so many patients there in their homes where they are hiding from society because they are afraid to walk to the grocery stores, they are afraid to go the the street.” “Our patient was called names and was humiliated. We very much hope that for this very special group of patients there is a hope that someday they will be able to go comfortably from their houses and enjoy the things we take for granted,” she added.

In response to the medical breakthrough, a British medical group led by Royal Free Hospital’s lead surgeon Dr Peter Butler, said they will finish the world’s first full face transplant within a year. “We hope to make an announcement about a full-face operation in the next 12 months. This latest operation shows how facial transplantation can help a particular group of the most severely facially injured people. These are people who would otherwise live a terrible twilight life, shut away from public gaze,” he said.
