    Package        : kfreebsd-9
    CVE ID         : CVE-2015-1414 CVE-2015-2923
    Debian Bug     : 779201 782735
    
    It was discovered that by sending crafted Router Advertisement packets,
    an attacker on the local network could lower the Current Hop Limit and
    cause the system to lose the ability to communicate with another IPv6
    node on a different network.
    
    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
    IGMP packets.
    
    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.
