Debian DLA-1992-1 : ghostscript security update

high Nessus Plugin ID 131035

Synopsis

The remote Debian host is missing a security update.

Description

Manfred Paul and Lukas Schauer reported that the .charkeys procedure in Ghostscript, the GPL PostScript/PDF interpreter, does not properly restrict privileged calls, which could result in bypass of file system restrictions of the dSAFER sandbox.

For Debian 8 'Jessie', this problem has been fixed in version 9.26a~dfsg-0+deb8u6.

We recommend that you upgrade your ghostscript 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.

Solution

Upgrade the affected packages.
