Multiple vulnerabilities have been found in GPL Ghostscript, the worst of which may allow execution of arbitrary code.

Affected packages

Background

Description

Multiple vulnerabilities have been discovered in GPL Ghostscript and the bundled OpenJPEG. Please review the CVE identifiers and GLSA-201612-26 (OpenJPEG) referenced below for additional information.

Note: GPL Ghostscript in Gentoo since app-text/ghostscript-gpl-9.20-r1 no longer bundles OpenJPEG.
