CVE-2024-33871

An issue was discovered in Artifex Ghostscript before 10.03.1. contrib/opvp/gdevopvp.c allows arbitrary code execution via a custom Driver library, exploitable via a crafted PostScript document. This occurs because the Driver parameter for opvp (and oprp) devices can have an arbitrary name for a dynamic library; this library is then loaded.

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):

Artifex Ghostscript before 10.03.0 sometimes has a stack-based buffer overflow via the CIDFSubstPath and CIDFSubstFont parameters.(CVE-2024-29507)

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: OPVP device arbitrary code execution via custom Driver library (CVE-2024-33871)

Multiple security issues were discovered in Ghostscript, the GPL PostScript/PDF interpreter, which could result in denial of service and potentially the execution of arbitrary code if malformed document files are processed.

These are all security issues fixed in the ghostscript-10.03.1-1.1 package on the GA media of openSUSE Tumbleweed.

It was discovered that Ghostscript did not properly restrict eexec seeds to those specified by the Type 1 Font Format standard when SAFER mode is used. An attacker could use this issue to bypass SAFER restrictions and cause unspecified impact. (CVE-2023-52722) This issue only affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 23.10.

Thomas Rinsma discovered that Ghostscript did not prevent changes to uniprint device argument strings after SAFER is activated, resulting in a format-string vulnerability. An attacker could possibly use this to execute arbitrary code. (CVE-2024-29510)

Zdenek Hutyra discovered that Ghostscript did not properly perform path reduction when validating paths. An attacker could use this to access file locations outside of those allowed by SAFER policy and possibly execute arbitrary code. (CVE-2024-33869)

Zdenek Hutyra discovered that Ghostscript did not properly check arguments when reducing paths. An attacker could use this to access file locations outside of those allowed by SAFER policy. (CVE-2024-33870)

Zdenek Hutyra discovered that the "Driver" parameter for Ghostscript's "opvp"/"oprp" device allowed specifying the name of an arbitrary dynamic library to load. An attacker could use this to execute arbitrary code. (CVE-2024-33871)
