CVE-2011-1770 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-1770):
  Integer underflow in the dccp_parse_options function (net/dccp/options.c) in
  the Linux kernel before 2.6.33.14 allows remote attackers to cause a denial
  of service via a Datagram Congestion Control Protocol (DCCP) packet with an
  invalid feature options length, which triggers a buffer over-read.

There are no longer any 2.x kernels available in the repository with the exception of sys-kernel/xbox-sources which is unsupported by security.
