Debian DSA-1461-1 : libxml2 - missing input validation

medium Nessus Plugin ID 29938
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.

Synopsis

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

Description

Brad Fitzpatrick discovered that the UTF-8 decoding functions of libxml2, the GNOME XML library, validate UTF-8 correctness insufficiently, which may lead to denial of service by forcing libxml2 into an infinite loop.

Solution

Upgrade the libxml2 packages.

For the old stable distribution (sarge), this problem has been fixed in version 2.6.16-7sarge1.

For the stable distribution (etch), this problem has been fixed in version 2.6.27.dfsg-2.
