Description Sean Amoss (RETIRED) gentoo-dev Security 2012-11-13 23:44:33 UTC 
From the oss-security mailing list at $URL:

  Marco d'Itri in Debian bug [1] has reported the following deficiency,
being present in 0.99.21 and possibly earlier versions of the Quagga 
routing suite:

A denial of service flaw was found in the way Quagga's ospf6d daemon
performed routes removal. In certain circumstances when removing the
route the ospf6d daemon terminated with assertion failure when trying
to determine / find, which route to remove. An OSPF6 router could use
this flaw to cause ospf6d on an adjacent router to abort.

Comment 1 Sergey Popov (RETIRED) gentoo-dev 2013-04-02 16:34:21 UTC 
This issue is not fixed with 0.99.22, as upstream says
Comment 2 Sergey Popov (RETIRED) gentoo-dev 2015-07-23 14:07:21 UTC 
still not fixed in 0.99.24.1 :-(

@maintainers is this bug stable? Can we send to glsa?

Comment 4 Sergey Popov (RETIRED) gentoo-dev 2017-07-03 07:38:39 UTC 
No, this is still not fixed upstream
Comment 5 Aaron Bauman (RETIRED) gentoo-dev 2018-01-30 00:51:27 UTC 
Still nothing from the original reporter following multiple releases of quagga and questions from upstream. Upstream is unable to produce still.  Minimal security impact.
