Debian DSA-2137-1 : libxml2 - several vulnerabilities

critical Nessus Plugin ID 51399
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.


Yang Dingning discovered a double free in libxml's Xpath processing, which might allow the execution of arbitrary code.


Upgrade the libxml2 packages.

For the stable distribution (lenny), this problem has been fixed in version 2.6.32.dfsg-5+lenny3.

For the upcoming stable distribution (squeeze) and the unstable distribution (sid), this problem has been fixed in version 2.7.8.dfsg-2.
