Debian DLA-3381-1 : ghostscript - LTS security update

critical Nessus Plugin ID 173849

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dla-3381 advisory.

 - In Artifex Ghostscript through 10.01.0, there is a buffer overflow leading to potential corruption of data internal to the PostScript interpreter, in base/sbcp.c. This affects BCPEncode, BCPDecode, TBCPEncode, and TBCPDecode. If the write buffer is filled to one byte less than full, and one then tries to write an escaped character, two bytes are written. (CVE-2023-28879)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the ghostscript packages.

For Debian 10 Buster, this problem has been fixed in version 9.27~dfsg-2+deb10u7.
