CVE-2013-1821
Ben Murphy discovered that unrestricted entity expansion in REXML can lead to a Denial of Service by consuming all host memory.
CVE-2013-4073
William (B.J.) Snow Orvis discovered a vulnerability in the hostname checking in Ruby's SSL client that could allow man-in-the-middle attackers to spoof SSL servers via valid certificate issued by a trusted certification authority.
For the oldstable distribution (squeeze), these problems have been fixed in version 1.9.2.0-2+deb6u1.
For the stable distribution (wheezy), these problems have been fixed in version 1.9.3.194-8.1+deb7u1.
For the unstable distribution (sid), these problems have been fixed in version 1.9.3.194-8.2.
We recommend that you upgrade your ruby1.9.1 packages.");
