Debian Security Advisory DSA-4972-1 security@debian.org
https://www.debian.org/security/ Salvatore Bonaccorso
September 10, 2021 https://www.debian.org/security/faq
- - -------------------------------------------------------------------------
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
