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.
CVE-2018-19134
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.
CVE-2018-19478
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
9.06~dfsg-2+deb8u13.
We recommend that you upgrade your ghostscript packages.
