Debian DLA-1839-1 : expat security update

high Nessus Plugin ID 126348

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that Expat, an XML parsing C library, did not properly handle XML input including XML names that contain a large number of colons, potentially resulting in denial of service.

For Debian 8 'Jessie', this problem has been fixed in version 2.1.0-6+deb8u5.

We recommend that you upgrade your expat packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
