Detailsinfo

A vulnerability was found in Artifex Ghostscript up to 10.7.x. It has been declared as critical. This vulnerability affects some unknown processing of the file base/sjpx_openjpeg.c of the component JPEG 2000 Output Adapter. The manipulation with an unknown input leads to a buffer overflow vulnerability. The CWE definition for the vulnerability is CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability was named CVE-2026-39919 since 04/07/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 350696 (Debian dsa-6516 : ghostscript - security update), which helps to determine the existence of the flaw in a target environment.
