9b5198e025901d7e83cb9d7ed6a8a856074baa405387532a1558ef7da79896f5Mandriva Linux Security Advisory 2010-188 - Some vulnerabilities were discovered and corrected in the Linux kernel. fs/namei.c in Linux kernel 2.6.18 through 2.6.34 does not always follow NFS automount symlinks, which allows attackers to have an unknown impact, related to LOOKUP_FOLLOW. The do_pages_move function in mm/migrate.c in the Linux kernel before 2.6.33-rc7 does not validate node values, which allows local users to read arbitrary kernel memory locations, cause a denial of service , and possibly have unspecified other impact by specifying a node that is not part of the kernel node set. Various other issues have been addressed.

ddce2a1f54158deb8c3002cf6fd5f7f63349871281f4dfeaa4907542189e2839Ubuntu Security Notice USN-807-1 - Michael Tokarev discovered that the RTL8169 network driver did not correctly validate buffer sizes. A remote attacker on the local network could send specially traffic traffic that would crash the system or potentially grant elevated privileges. Julien Tinnes and Tavis Ormandy discovered that when executing setuid processes the kernel did not clear certain personality flags. A local attacker could exploit this to map the NULL memory page, causing other vulnerabilities to become exploitable. Ubuntu 6.06 was not affected. Matt T. Yourst discovered that KVM did not correctly validate the page table root. A local attacker could exploit this to crash the system, leading to a denial of service. Ubuntu 6.06 was not affected. Ramon de Carvalho Valle discovered that eCryptfs did not correctly validate certain buffer sizes. A local attacker could create specially crafted eCryptfs files to crash the system or gain elevated privileges. Ubuntu 6.06 was not affected.
