function can be used by local attackers to gain root
privileges. (CVE-2009-2692)

- A kernel stack overflow when mounting eCryptfs
filesystems in parse_tag_11_packet() was fixed. Code
execution might be possible of ecryptfs is in use.

- A kernel heap overflow when mounting eCryptfs
filesystems in parse_tag_3_packet() was fixed. Code
execution might be possible of ecryptfs is in use.

The compiler option -fno-delete-null-pointer-checks was added to the
kernel build, and the -fwrapv compiler option usage was fixed to be
used everywhere. This works around the compiler removing checks too

was fixed. This is probably exploitable only in the
local network. (CVE-2009-1389)
