CVE-2026-39919 (GCVE-0-2026-39919)

Vulnerability from cvelistv5 – Published: 2026-09-15 14:26 – Updated: 2026-10-01 15:19 X_Open Source

Title

Ghostscript < 10.08.0 Heap Buffer Overflow via JPEG 2000 Output Adapter

Summary

Ghostscript before 10.08.0 contains a heap-based buffer overflow vulnerability in the JPEG 2000 output adapter (base/sjpx_openjpeg.c) that allows attackers to cause memory corruption by supplying a crafted PDF containing a JPEG 2000 image with mismatched component subsampling factors. When image components declare different subsampling values, the non-samescale sub-byte-depth output path allocates a row buffer sized for packed output but writes a full byte per output column regardless of bit depth, overflowing the allocation and corrupting internal chunk-allocator metadata to achieve code execution.
