Description Stefan Behte (RETIRED) gentoo-dev Security 2009-01-13 23:49:08 UTC 
CVE-2009-0065 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-0065):
  Buffer overflow in net/sctp/sm_statefuns.c in the Stream Control
  Transmission Protocol (sctp) implementation in the Linux kernel
  before 2.6.28-git8 allows remote attackers to have an unknown impact
  via an FWD-TSN (aka FORWARD-TSN) chunk with a large stream ID.
Comment 1 Stefan Behte (RETIRED) gentoo-dev Security 2009-05-05 20:42:10 UTC 
This is remotely exploitable and gives a Rootshell, see http://kernelbof.blogspot.com/2009/04/kernel-memory-corruptions-are-not-just.html
SCTP is not enabled by default AFAIK, but we still might want to patch this a bit faster...
Comment 2 Gordon Malm (RETIRED) gentoo-dev 2009-05-05 20:57:16 UTC 
Already fixed in all hardened kernels.
Comment 3 kfm 2009-07-21 21:36:55 UTC 
RE Comment 2 - Indeed. Removing alias.

PS: genpatches-2.6.27-11 added 2.6.27.13. genpatches-2.6.28-3 added 2.6.28.2. hardened-sources-2.6.25-r13 is unaffected as the patch was added independently in the preceding patchset.
