Debian DSA-1695-1 : ruby1.8, ruby1.9 - memory leak

medium Nessus Plugin ID 35294
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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


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.


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.
