Summary

Additionally, it was discovered that the patch applied to kfreebsd-9 in
DSA-3175-1 for CVE-2015-1414 was incomplete. For reference the original
advisory text follows:

Mateusz Kocielski and Marek Kroemeke discovered that an integer overflow
in IGMP processing may result in denial of service through malformed

For the oldstable distribution (wheezy), these problems have been fixed
in version 9.0-10+deb70.10.

We recommend that you upgrade your kfreebsd-9 packages.
