USN-1380-1: Linux kernel vulnerabilities
First published: Wed Feb 29 2012(Updated: )
A flaw was discovered in the TOMOYO LSM's handling of mount system calls. An unprivileged user could oops the system causing a denial of service. (CVE-2011-2518) A bug was discovered in the Linux kernel's calculation of OOM (Out of memory) scores, that would result in the wrong process being killed. A user could use this to kill the process with the highest OOM score, even if that process belongs to another user or the system. (CVE-2011-4097) A flaw was found in the linux kernels IPv4 IGMP query processing. A remote attacker could exploit this to cause a denial of service. (CVE-2012-0207)
