CVE-2023-36664

Artifex Ghostscript through 10.01.2 mishandles permission validation for pipe devices (with the %pipe% prefix or the | pipe character prefix).

Artifex Ghostscript before 10.01.2 mishandles permission validation for pipe devices (with the %pipe% prefix or the | pipe character prefix).

Ghostscript is an interpreter for PostScript™ and Portable Document Format (PDF) files. Ghostscript consists of a PostScript interpreter layer, and a graphics library.

Security Fix(es):

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)

Artifex Ghostscript through 10.01.2 mishandles permission validation for pipe devices (with the %pipe% prefix or the | pipe character prefix).(CVE-2023-36664)

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)

The Ghostscript suite contains utilities for rendering PostScript and PDF documents. Ghostscript translates PostScript code to common bitmap formats so that the code can be displayed or printed.

Security Fix(es):

• ghostscript: vulnerable to OS command injection due to mishandles permission validation for pipe devices (CVE-2023-36664)

These are all security issues fixed in the ghostscript-9.56.1-4.1 package on the GA media of openSUSE Tumbleweed.

This update for ghostscript fixes the following issues:

• CVE-2023-36664: Fixed permission validation mishandling for pipe devices with the %pipe% prefix or the | pipe character prefix (bsc#1212711).

This update for ghostscript fixes the following issues:

• CVE-2023-36664: Fixed permission validation mishandling for pipe devices with the %pipe% prefix or the | pipe character prefix (bsc#1212711).

It was discovered that Ghostscript incorrectly handled pipe devices. If a user or automated system were tricked into opening a specially crafted PDF file, a remote attacker could use this issue to execute arbitrary code.
