CVE-2024-33870

An issue was discovered in Artifex Ghostscript before 10.03.1. There is path traversal (via a crafted PostScript document) to arbitrary files if the current directory is in the permitted paths. For example, there can be a transformation of ../../foo to ./../../foo and this will grant access if ./ is permitted.

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):

An issue was discovered in Artifex Ghostscript before 10.03.1. psi/zmisc1.c, when SAFER mode is used, allows eexec seeds other than the Type 1 standard.(CVE-2023-52722)

An issue was discovered in Artifex Ghostscript before 10.03.1. Path traversal and command execution can occur (via a crafted PostScript document) because of path reduction in base/gpmisc.c. For example, restrictions on use of %pipe% can be bypassed via the aa/../%pipe%command# output filename.(CVE-2024-33869)

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: format string injection leads to shell command execution (SAFER bypass) (CVE-2024-29510)

• ghostscript: path traversal and command execution due to path reduction (CVE-2024-33869)

• ghostscript: path traversal to arbitrary files if the current directory is in the permitted paths (CVE-2024-33870)

• CVE-2024-33870: fix path traversal vulnerability to prevent unauthorized access to arbitrary files by restricting access to permitted paths

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.

This update for ghostscript fixes the following issues:

• CVE-2024-29510: Fixed an arbitrary path traversal when running in a permitted path (bsc#1226945).
• CVE-2024-33870: Fixed a format string injection that could lead to command execution (bsc#1226944).
• CVE-2024-33869: Fixed a path validation bypass that could lead to path traversal (bsc#1226946).

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)
