CVE-2024-29507Public exploitNetwork attack vector

Document-triggered crash via unchecked font-parameter copies

Published Jul 3, 2024 · Updated Dec 3, 2024

Stack-based buffer overflow in Artifex Ghostscript before 10.03.0 allows attackers to crash the interpreter with crafted input. In pdfi_open_CIDFont_substitute_file, unchecked memcpy calls copy oversized CIDFSubstPath or CIDFSubstFont values into a fixed 4096-byte fontfname stack buffer. Exploitation requires processing attacker-controlled PostScript that invokes the PDF interpreter with Type0 font substitution, and the demonstrated impact is a process crash.
