Debian DSA-5038-1 : ghostscript - security update

medium Nessus Plugin ID 156563

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 / 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5038 advisory.

 Multiple security issues were discovered in Ghostscript, the GPL PostScript/PDF interpreter, which could result in denial of service and potentially the execution of arbitrary code if malformed document files are processed. For the oldstable distribution (buster), these problems have been fixed in version 9.27~dfsg-2+deb10u5. For the stable distribution (bullseye), these problems have been fixed in version 9.53.3~dfsg-7+deb11u2. 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 these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the ghostscript packages.

For the stable distribution (bullseye), these problems have been fixed in version 9.53.3~dfsg-7+deb11u2.
