FreeBSD : libxml2 -- Denial of service (0642b064-56c4-11e4-8b87-bcaec565249c)

medium Nessus Plugin ID 78577

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

RedHat reports :

A denial of service flaw was found in libxml2, a library providing support to read, modify and write XML and HTML files. A remote attacker could provide a specially crafted XML file that, when processed by an application using libxml2, would lead to excessive CPU consumption (denial of service) based on excessive entity substitutions, even if entity substitution was disabled, which is the parser default behavior.

Solution

Update the affected packages.
