14 DAY TRIAL // A security vulnerability that was discovered in the Linux kernel affecting the Ubuntu 10.04 LTS (Lucid Lynx) operating system has been announced by Canonical.
These are the kernel vulnerabilities found in the Linux kernel packages: CVE-2012-6542, CVE-2012-6544, CVE-2012-6545, CVE-2012-6546, CVE-2012-6548, CVE-2013-0228, CVE-2013-0349, CVE-2013-1774, and CVE-2013-1796. Several security issues have been fixed in the kernel.
For example, an information leak has been found in the Linux kernel's getsockname implementation, for Logical Link Layer (llc) sockets. A local user could exploit this flaw to examine some of the kernel's stack memory.
The security flaws can be fixed if you upgrade your system(s) to thelinux-image-2.6.32-46 (2.6.32-46.105).
Don't forget to reboot your computer after the upgrade!
ATTENTION: Due to an unavoidable ABI change, the kernel packages have a new version number, which will force you to reinstall and recompile all third-party kernel modules you might have installed. Moreover, if you use the linux-restricted-modules package, you have to update it as well to get modules that work with the new Linux kernel version.
