Source: imagemagick

Hi,

The following vulnerability was published for imagemagick.

CVE-2025-65955[0]:
| 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.
