Debian DSA-4972-1 : ghostscript - security update

critical Nessus Plugin ID 153215

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 11 host has packages installed that are affected by a vulnerability as referenced in the dsa-4972 advisory.

It was discovered that Ghostscript, the GPL PostScript/PDF interpreter, does not properly validate access for the %pipe%, %handle% and %printer% io devices, which could result in the execution of arbitrary code if a malformed Postscript file is processed (despite the -dSAFER sandbox being enabled). For the stable distribution (bullseye), this problem has been fixed in version 9.53.3~dfsg-7+deb11u1. We recommend that you upgrade your ghostscript packages. For the detailed security status of ghostscript please refer to its security tracker page at: https://security-tracker.debian.org/tracker/ghostscript

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the ghostscript packages.

For the stable distribution (bullseye), this problem has been fixed in version 9.53.3~dfsg-7+deb11u1.
