Ubuntu 14.04 LTS / 16.04 LTS / 16.10 / 17.04 : freetype vulnerabilities (USN-3282-1)

critical Nessus Plugin ID 100101

Language:

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

It was discovered that FreeType did not correctly handle certain malformed font files. If a user were tricked into using a specially crafted font file, a remote attacker could cause FreeType to crash, resulting in a denial of service, or possibly execute arbitrary code.

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

Solution

Update the affected libfreetype6 package.
