USN-691-1: Ruby vulnerability

16 December 2008

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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 8.10

In general, a standard system upgrade is sufficient to effect the
necessary changes.
