Debian Security Advisory
DSA-4972-1 ghostscript -- security update
- Date Reported:
- 10 Sep 2021
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 994011.
In Mitre's CVE dictionary: CVE-2021-3781.
- More information:
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.
