CVE-2023-52722

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.

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.

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

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)

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.(CVE-2024-33870)

• CVE-2023-52722: reject non-standard eexec seeds in SAFER mode (psi/zmisc1.c)

• CVE-2023-52722: reject non-standard eexec seeds in SAFER mode (psi/zmisc1.c)

An issue was discovered in Artifex Ghostscript through 10.01.0. psi/zmisc1.c, when SAFER mode is used, allows eexec seeds other than the Type 1 standard. (CVE-2023-52722)

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

This update for ghostscript fixes the following issues:

• CVE-2023-52722: Do not allow eexec seeds other than the Type 1 standard while using SAFER mode (bsc#1223852).

This update for ghostscript fixes the following issues:

This update for ghostscript fixes the following issues:

• CVE-2023-52722: Do not allow eexec seeds other than the Type 1 standard while using SAFER mode (bsc#1223852).

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)
