[USN-1534-1] Linux kernel (EC2) vulnerabilities

Severity High

CVEs 2

Several security issues were fixed in the kernel.

An error was discovered in the Linux kernel's network TUN/TAP device
implementation. A local user with access to the TUN/TAP interface (which is
not available to unprivileged users until granted by a root user) could
exploit this flaw to crash the system or potential gain administrative
privileges. (CVE-2012-2136)

An error was discovered in the Linux kernel's memory subsystem (hugetlb).
An unprivileged local user could exploit this flaw to cause a denial of
