[DLA 224-1] ruby1.8 security update

Package : ruby1.8
Version : 1.8.7.302-2squeeze4
CVE ID : CVE-2015-1855

It was discovered that the Ruby OpenSSL extension, part of the
interpreter for the Ruby language, did not properly implement hostname
matching, in violation of RFC 6125. This could allow remote attackers to
perform a man-in-the-middle attack via crafted SSL certificates.

For the oldoldstable distribution (squeeze), this problem has been
fixed in version 1.8.7.302-2squeeze4.

For the oldstable distribution (wheezy), this problem was fixed in
version 1.8.7.358-7.1+deb7u3.

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.
