Synopsis :

The remote Fedora host is missing a security update.

Description :

This update includes expat 2.1.0, which fixes includes a fix for a
security issue.

A specially crafted set of keys could trigger hash function
collisions, which degrade dictionary performance by changing hash
table operations complexity from an expected/average O(1) to the worst
case O(n). Reporters were able to find colliding strings efficiently
using meet in the middle attack. (CVE-2012-0876)

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
