Debian DLA-1973-1 : libxslt security update

critical Nessus Plugin ID 130286

Synopsis

The remote Debian host is missing a security update.

Description

A security vulnerability was discovered in libxslt, a XSLT 1.0 processing library written in C.

In xsltCopyText in transform.c, a pointer variable is not reset under certain circumstances. If the relevant memory area happened to be freed and reused in a certain way, a bounds check could fail and memory outside a buffer could be written to, or uninitialized data could be disclosed.

For Debian 8 'Jessie', this problem has been fixed in version 1.1.28-2+deb8u6.

We recommend that you upgrade your libxslt 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.
