Test ID:1.3.6.1.4.1.25623.1.0.703597
Category:Debian Local Security Checks
Title:Debian: Security Advisory (DSA-3597-1)
Summary:The remote host is missing an update for the Debian 'expat' package(s) announced via the DSA-3597-1 advisory.
Description:Summary:
The remote host is missing an update for the Debian 'expat' package(s) announced via the DSA-3597-1 advisory.

Vulnerability Insight:
Two related issues have been discovered in Expat, a C library for parsing XML.

CVE-2012-6702

It was introduced when CVE-2012-0876 was addressed. Stefan Sorensen discovered that the use of the function XML_Parse() seeds the random number generator generating repeated outputs for rand() calls.

CVE-2016-5300

It is the product of an incomplete solution for CVE-2012-0876. The parser poorly seeds the random number generator allowing an attacker to cause a denial of service (CPU consumption) via an XML file with crafted identifiers.

You might need to manually restart programs and services using expat libraries.

For the stable distribution (jessie), these problems have been fixed in version 2.1.0-6+deb8u3.

For the unstable distribution (sid), these problems have been fixed in version 2.1.1-3.

We recommend that you upgrade your expat packages.

Affected Software/OS:
'expat' package(s) on Debian 8.

Solution:
Please install the updated package(s).

CVSS Score:
7.8
