CVE-2026-39919 Ghostscript < 10.08.0 Heap Buffer Overflow via JPEG 2000 Output Adapter

Ghostscript before 10.08.0 contains a heap-based buffer overflow vulnerability in the JPEG 2000 output adapter base/sjpxopenjpeg.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...

CVE-2026-39919

Ghostscript before 10.08.0 is affected by a heap-based buffer overflow in the JPEG 2000 output adapter (base/sjpx_openjpeg.c). The root cause is a sizing mismatch: when image components declare different subsampling factors, the non-samescale sub-byte-depth path allocates a row buffer sized for p...
