Debian DLA-2415-1 : freetype security update

medium Nessus Plugin ID 141910

Synopsis

The remote Debian host is missing a security update.

Description

Sergei Glazunov discovered a heap-based buffer overflow vulnerability in the handling of embedded PNG bitmaps in FreeType. Opening malformed fonts may result in denial of service or the execution of arbitrary code.

For Debian 9 stretch, this problem has been fixed in version 2.6.3-3.2+deb9u2.

We recommend that you upgrade your freetype packages.

For the detailed security status of freetype please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/freetype

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.
