DESCRIPTION

* CVE-2013-7263, CVE-2013-7265: Information leak in IPv4, IPv6 and PhoNet socket
recvmsg.

The IPv4, IPv6 and PhoNet recvmsg(2) ioctls do not initialise the length a
network address causing the contents of kernel memory to be disclosed to
userspace under certain circumstances.


* CVE-2013-2929: Incorrect permissions check in ptrace with dropped privileges.

The ptrace subsystem incorrectly checked the state of the fs.suid_dumpable
sysctl allowing a user to ptrace attach to a process if it had dropped
privileges to that user.
