Summary: Ruby vulnerability
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. (CVE-2008-3443)
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.
