New! Plugin Severity Now Using CVSS v3

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the Ruby packages.

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.
