Debian DLA-2257-1 : pngquant security update

Medium Nessus Plugin ID 137860


The remote Debian host is missing a security update.


It was found that pngquant, a PNG (Portable Network Graphics) image optimising utility, is susceptible to a buffer overflow write issue triggered by a maliciously crafted png image, which could lead into denial of service or other issues.

For Debian 8 'Jessie', this problem has been fixed in version 2.3.0-1+deb8u1.

We recommend that you upgrade your pngquant 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.


Upgrade the affected pngquant package.
