Description

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-9 and 6.9.13-34, there is a vulnerability in ImageMagick’s Magick++ layer that manifests when Options::fontFamily is invoked with an empty string. Clearing a font family calls RelinquishMagickMemory on _drawInfo->font, freeing the font string but leaving _drawInfo->font pointing to freed memory while _drawInfo->family is set to that (now-invalid) pointer. Any later cleanup or reuse of _drawInfo->font re-frees or dereferences dangling memory. DestroyDrawInfo and other setters (Options::font, Image::font) assume _drawInfo->font remains valid, so destruction or subsequent updates trigger crashes or heap corruption. This vulnerability is fixed in 7.1.2-9 and 6.9.13-34.

FeehiCMS version 2.1.1 has a Remote Code Execution via Unrestricted File Upload in Ad Management. FeehiCMS version 2.1.1 allows authenticated remote attackers to upload files that the server later executes (or stores in an executable location) without sufficient validation, sanitization, or execution restrictions. An authenticated remote attacker can upload a crafted PHP file and cause the application or web server to execute it, resulting in remote code execution (RCE).
