Debian DLA-981-1 : apng2gif security update

high Nessus Plugin ID 100673

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that apng2gif was vulnerable to an integer overflow resulting in a heap-based buffer over-read/write. A remote attacker could use this flaw to cause a denial of service (application crash) via a crafted APNG file.

For Debian 7 'Wheezy', these problems have been fixed in version 1.5-1+deb7u1.

We recommend that you upgrade your apng2gif 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 apng2gif package.
