Debian Security Advisory DSA-4972-1 [email protected]

Package : ghostscript
CVE ID : CVE-2021-3781
Debian Bug : 994011

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

Further information about Debian Security Advisories, how to apply
these updates to your system and frequently asked questions can be
