Vulnerability Title
Imagemagick Has Global Buffer Overflow (OOB Read) via Negative Pixel Index in UIL and XPM Writer
Vulnerability Description
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.

ImageMagick 缓冲区错误漏洞
Vulnerability Description
ImageMagick是ImageMagick开源的一套开源的图像处理软件。可读取、转换或写入多种格式的图片。 ImageMagick 7.1.2-15之前版本和6.9.13-40之前版本存在缓冲区错误漏洞，该漏洞源于UIL和XPM图像编码器在使用GetPixelIndex返回值作为数组下标前未验证其有效性，可能导致全局缓冲区溢出读取，造成信息泄露或进程崩溃。
