Description Alex Legler (RETIRED) archtester Gentoo Infrastructure gentoo-dev Security 2012-01-24 13:59:01 UTC
Julien Tinnes reported that bip does not check the number of open file descriptors against FD_SETSIZE, resulting in a buffer overflow that is supposed to be exploitable.

Fix: https://projects.duckcorp.org/projects/bip/repository/revisions/222a33cb84a2e52ad55a88900b7895bf9dd0262c

I'm assuming there's a release right around the corner.
Comment 2 Alex Legler (RETIRED) archtester Gentoo Infrastructure gentoo-dev Security 2012-01-27 17:09:11 UTC
No release yet, went for a revbump.

Arches, please test and mark stable:

  Buffer overflow in Bip 0.8.8 and earlier might allow remote authenticated
  users to execute arbitrary code via vectors involving a series of TCP
  connections that triggers use of many open file descriptors.
