Debian DLA-1912-1 : expat security update

high Nessus Plugin ID 128557

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was a heap-based buffer overread vulnerability in expat, an XML parsing library.

A specially crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer overread.

For Debian 8 'Jessie', this issue has been fixed in expat version 2.1.0-6+deb8u6.

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.
