Package        : ghostscript
CVE ID         : CVE-2023-28879
Debian Bug     : 1033757

It was discovered that Ghostscript, the GPL PostScript/PDF interpreter,
is prone to a buffer overflow vulnerability in the (T)BCP encoding
filters, which could result in the execution of arbitrary code if
malformed document files are processed (despite the -dSAFER sandbox
being enabled).

For the stable distribution (bullseye), this problem has been fixed in
version 9.53.3~dfsg-7+deb11u4.

We recommend that you upgrade your ghostscript packages.
