Arbitrary code execution via attacker-named driver library
Published Jul 3, 2024 · Updated Aug 2, 2024
Code injection in Artifex Ghostscript before 10.03.1 allows remote attackers to execute arbitrary code via a crafted PostScript document. The OPVP and OPRP device code in contrib/opvp/gdevopvp.c accepts an arbitrary Driver library name and loads that library without restricting it to trusted drivers. Exploitation requires Ghostscript to process the document with an affected device compiled in, after which the library runs with the interpreter's privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
