Kerentanan Heap-based Buffer Overflow. Skor CVSS 3.1 9.8 (Critical) menurut vulncheck.com.
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.
