Synopsis

The pnmtopng utility, part of the Netpbm tools, contains a vulnerability which can potentially result in the execution of arbitrary code.

Background

Netpbm is a package of 220 graphics programs and a programming library, including pnmtopng, a tool to convert PNM image files to the PNG format.

media-libs/netpbm	< 10.29	>= 10.29	All supported architectures

Description
