This blog follows the breeding season of Gentoo penguins at the Gars O'Higgins research facility, as well as the King, Adelie, and Gentoo penguins at South Georgia Island. This blog will consist of images taken from the nesting site at O'Higgins Station, the surrounding area on the Antarctic Peninsula, and the beach on South Georgia Island.
Red Hat Product Security recently celebrated our 15th anniversary this summer and while I cannot claim to have been with Red Hat for that long (although I’m coming up on 8 years myself), I’ve watched the changes from the “0day” of the Red Hat Security Response Team to today. In fact, our SRT was the basis for the security team that Mandrakesoft started back in the day.
In 1999, I started working for Mandrakesoft, primarily as a packager/maintainer. The offer came, I suspect, because of the amount of time I spent volunteering to maintain packages in the distribution. I also was writing articles for TechRepublic at the time, so I also ended up being responsible for some areas of documentation, contributing to the manual we shipped with every boxed set we sold (remember when you bought these things off the shelf?).
Researchers have devised an attack that gains unfettered "root" access to a large number of Android phones, exploiting a relatively new type of bug that allows adversaries to manipulate data stored in memory chips.
The breakthrough has the potential to make millions of Android phones vulnerable, at least until a security fix is available, to a new form of attack that seizes control of core parts of the operating system and neuters key security defenses. Equally important, it demonstrates that the new class of exploit, dubbed Rowhammer, can have malicious and far-reaching effects on a much wider number of devices than was previously known, including those running ARM chips.
Previously, some experts believed Rowhammer attacks that altered specific pieces of security-sensitive data weren't reliable enough to pose a viable threat because exploits depended on chance hardware faults or advanced memory-management features that could be easily adapted to repel the attacks. But the new proof-of-concept attack developed by an international team of academic researchers is challenging those assumptions.
