ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a heap buffer overflow write vulnerability exists in ReadYUVImage() (coders/yuv.c) when processing malicious YUV 4:2:2 (NoInterlace) images. The pixel-pair loop writes one pixel beyond the allocated row buffer. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
AnalysisAI
ImageMagick versions prior to 7.1.2-15 and 6.9.13-40 are vulnerable to a heap buffer overflow in the YUV image decoder that allows remote attackers to trigger a denial of service condition by processing specially crafted YUV 4:2:2 images. The vulnerability stems from an off-by-one write error in the pixel processing loop that exceeds allocated buffer boundaries. …
