Debian DLA-1499-1 : discount security update

medium Nessus Plugin ID 117367

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Several heap-based buffer over-reads were found in discount, an implementation of the Markdown markup language in C, that allowed remote attackers to cause a denial of service via specially crafted files.

For Debian 8 'Jessie', these problems have been fixed in version 2.1.7-1+deb8u1.

We recommend that you upgrade your discount 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.
