Multiple buffer overflows in ha.c in the mipv6 daemon in UMIP 0.4
allow remote attackers to have an unspecified impact via a crafted (1)
ND_OPT_PREFIX_INFORMATION or (2) ND_OPT_HOME_AGENT_INFO packet.


The patch supplied by Sebastian Krahmer is here:

Alternative patches on umip.org are here:

Either patch should address both this issue and CVE-2010-2522.

Comment 2 Vincent Danen 2010-07-13 22:09:50 UTC
Created mipv6-daemon tracking bugs for this issue

Affects: fedora-all [bug 614239]

Comment 3 Tomas Hoger 2011-02-03 09:02:31 UTC
This is fixed in all current Fedora versions.  RHEL-6 packages were patched before GA.

Statement:

The mipv6-daemon packages in Red Hat Enterprise Linux 6 are not vulnerable to this issue, as they contain a backported patch correcting this flaw.
