CVE-2023-38560

Local denial of service via glyph-name integer overflow

Published Aug 1, 2023 · Updated Nov 20, 2025

Integer overflow in Ghostscript allows local attackers to cause a denial of service when converting crafted PCL files to PDF. The pl_glyph_name function in pcl/pl/plfont.c computes glyph-name lengths with an overflowing integer during PCL parsing, disrupting conversion. A local user must provide or cause processing of the crafted PCL input; the documented consequence is service interruption without confidentiality or integrity impact.
