Ubuntu Security Notice USN-691-1 - Laurent Gaffie discovered that Ruby did not properly check for memory allocation failures. If a user or automated system were tricked into running a malicious script, an attacker could cause a denial of service. This update also fixes a regression in the upstream patch previously applied to fix CVE-2008-3790. The regression would cause parsing of some XML documents to fail.
