ruby1.8 ruby1.9 - denial of service

The regular expression engine of Ruby, a scripting language, contains a
memory leak which can be triggered remotely under certain circumstances,
leading to a denial of service condition (CVE-2008-3443).

In addition, this security update addresses a regression in the REXML
XML parser of the ruby1.8 package; the regression was introduced in
DSA-1651-1.

For the stable distribution (etch), this problem has been fixed in version
1.8.5-4etch4 of the ruby1.8 package, and version 1.9.0+20060609-1etch4
of the ruby1.9 package.

For the unstable distribution (sid), this problem has been fixed in
version 1.8.7.72-1 of the ruby1.8 package. The ruby1.9 package will be
fixed soon.

We recommend that you upgrade your Ruby packages.
