Linux kernel built with Datagram Congestion Control Protocol(DCCP) with
the TCP-Friendly Rate Control(TRFC) mechanism is vulnerable to an information
leakage flaw. It occurs while doing an getsockopt call on the CCID3 socket.
A user/program could use this flaw to leak kernel memory bytes.
This issue does not affect the versions of the kernel package as shipped with
Red Hat Enterprise Linux 5, 6 and Red Hat Enterprise MRG 2.
