USN-6835-1: Ghostscript vulnerabilities

First published: Mon Jun 17 2024(Updated: )

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)
