The ReadJNGImage and ReadOneJNGImage functions in coders/png.c in GraphicsMagick 1.3.26 do not properly manage image pointers after certain error conditions, which allows remote attackers to conduct use-after-free attacks via a crafted file, related to a ReadMNGImage out-of-order CloseBlob call. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-11403.

Security readout for executives and security teams

GraphicsMagick 1.3.26 can mishandle memory while reading crafted JNG/MNG-related image data after certain errors. If a service processes attacker-supplied images with this version, the crash or memory corruption risk sits in the image-processing path, not in normal web content alone. Exposure is most likely where GraphicsMagick 1.3.26 processes untrusted images, including upload, thumbnailing, conversion, document-ingestion, or media-processing workflows. The provided data does not identify other affected versions. Prioritize remediation for internet-facing upload or conversion services using GraphicsMagick 1.3.26. For internal-only systems without untrusted image ingestion, urgency is lower but still warrants patch confirmation because memory-safety flaws can destabilize processing services. Mitigation focus: Inventory systems and containers using GraphicsMagick 1.3.26.; Apply vendor or distribution updates that include the referenced GraphicsMagick fix.; Verify patched builds include changes from revision 98721124e51f..
