Heap buffer overflow with attacker-controlled data in XBM parser

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-13 and 6.9.13-38, a heap buffer overflow vulnerability in the XBM image decoder (ReadXBMImage) allows an attacker to write controlled data past the allocated heap buffer when processing a maliciously crafted image file. Any operation that reads or identifies an image can trigger the overflow, making it exploitable via common image upload and processing pipelines. Versions 7.1.2-13 and 6.9.13-38 fix the issue.

堆缓冲区溢出

ImageMagick 输入验证错误漏洞

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 7.1.2-13之前版本和6.9.13-38之前版本存在输入验证错误漏洞，该漏洞源于XBM图像解码器存在堆缓冲区溢出，可能导致处理恶意图像文件时写入受控数据。
