Comment 1 GLSAMaker/CVETool Bot gentoo-dev 2016-03-13 14:18:22 UTC
CVE-2016-2342 (
  Quagga is a software routing suite that implements numerous routing
  protocols for Unix-based platforms. A memcpy function in the VPNv4 NLRI
  parser of bgp_mplsvpn.c does not properly check the upper-bound length of
  received Labeled-VPN SAFI routes data, which may allow for arbitrary code
  execution on the stack. Note that hosts are only vulnerable if bgpd is
  running with BGP peers enabled for VPNv4, which is not a default

The ebuilds must be removed from the tree.  Please let us know when you can remove them.  Thanks.

They must not, they should me removed, but until they are not - we can keep them masked per our policy.

I will keep them masked until quagga team will sort out all problems in new releases. In some OSPF configurations new releases of quagga just crashes, no solution provided for now. 

This particular bug is about vulnerability in bgpd. I think that it is unreasonable to let OSPF users suffer from regression, because of fixing vulnerability in bgpd, which maybe even not used by them
