EulerOS 2.0 SP8 : ghostscript (EulerOS-SA-2023-3126)

critical Nessus Plugin ID 188823

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the ghostscript packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - 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)

 - A buffer overflow flaw was found in base/gdevdevn.c:1973 in devn_pcx_write_rle() in ghostscript. This issue may allow a local attacker to cause a denial of service via outputting a crafted PDF file for a DEVN device with gs. (CVE-2023-38559)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected ghostscript packages.
