Dirty Cow, Ubuntu @ 12, Save a Penguin
Dirty Cow is a local privilege vulnerability that can allow one to gain root access. Specifically, "race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system." Linus signed off and pushed the patch to git a few days ago and distributions are currently updating their products. This is considered a critical bug and users are encouraged to update as soon as possible because researchers have found code in the wild to exploit it. Worse still, the exploit leaves little or no trace of being compromised. So, keep an eye on your update applets or security advisories over the next few days. Since this bug has been in existence for so long, Kees Cook had to revise his critical bug lifetime average from 3.3 to 5.2 years, while the overall average for all bugs increased only slightly.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
