CVE-2022-1350Public exploitNetwork attack vector

Memory corruption via improper chunk object release

Published Apr 14, 2022 · Updated Apr 15, 2025

Memory corruption in GhostPCL 9.55.0 allows remote attackers to crash the interpreter by inducing processing of a malicious PCL file. The chunk_free_object function in gsmchunk.c improperly releases chunk-managed objects during PCL-to-PDF conversion, leading to an out-of-bounds write. Successful exploitation requires user interaction to process the file; the CNA reports low availability impact, while NVD assesses broader memory-corruption effects.
