[DLA 1620-1] ghostscript security update
2 January 2019
AusCERT Security Bulletin Summary
Operating System: Debian GNU/Linux 8
Impact/Access: Execute Arbitrary Code/Commands -- Remote with User Interaction
Denial of Service -- Remote with User Interaction
CVE Names: CVE-2018-19478 CVE-2018-19134
- --------------------------BEGIN INCLUDED TEXT--------------------
Package : ghostscript
Version : 9.06~dfsg-2+deb8u13
CVE ID : CVE-2018-19134 CVE-2018-19478
Some vulnerabilities were discovered in ghostscript, an interpreter for the
PostScript language and for PDF.
The setpattern operator did not properly validate certain types. A specially
crafted PostScript document could exploit this to crash Ghostscript or,
possibly, execute arbitrary code in the context of the Ghostscript process.
This is a type confusion issue because of failure to check whether the
Implementation of a pattern dictionary was a structure type.
Attempting to open a carefully crafted PDF file results in long-running
computation. A sufficiently bad page tree can lead to us taking significant
amounts of time when checking the tree for recursion.
For Debian 8 "Jessie", these problems have been fixed in version
We recommend that you upgrade your ghostscript packages.
