Description Prasad J Pandit 2013-03-15 08:56:37 EDT 
Linux kernel built with XFRM framework support is vulnerable to a memory
leakage flaw. It occurs when a user creates a new state or updates an
existing one but does not supply the bytes for the whole ESN replay window
and the kernel copies heap bytes into the replay bitmap follow the
XFRMA_REPLAY_ESN_VAL netlink attribute.

A privileged(CAP_NET_ADMIN) user could use this flaw to leak up to ~3.5kB of
kernel heap memory.
