Lifecycle Timeline
3DescriptionNVD
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, the UIL and XPM image encoder do not validate the pixel index value returned by GetPixelIndex() before using it as an array subscript. In HDRI builds, Quantum is a floating-point type, so pixel index values can be negative. An attacker can craft an image with negative pixel index values to trigger a global buffer overflow read during conversion, leading to information disclosure or a process crash. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
AnalysisAI
ImageMagick's UIL and XPM image encoders fail to validate pixel index values before using them as array subscripts, allowing an attacker to craft malicious images that trigger out-of-bounds reads in HDRI builds. Exploitation can result in information disclosure or denial of service through process crashes. …
