Several vulnerabilities have been discovered in the interpreter for
the Ruby language, which may lead to denial of service and other
security problems. The Common Vulnerabilities and Exposures project
identifies the following problems:

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.
