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.

## Withdrawn Advisory This advisory has been withdrawn because it does not affect the ImageMagick project's NuGet packages.

### Original Description We believe that we have discovered a potential security vulnerability in ImageMagick’s Magick++ layer that manifests when `Options::fontFamily` is invoked with an empty string.

**Vulnerability Details** - 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.

```cpp if (family_.length() == 0) { _drawInfo->family=(char *) RelinquishMagickMemory(_drawInfo->font); DestroyString(RemoveImageOption(imageInfo(),"family")); } ```

- **CWE-416 (Use After Free):** `_drawInfo->font` is left dangling yet still reachable through the Options object. - **CWE-415 (Double Free):** DrawInfo teardown frees `_drawInfo->font` again, provoking allocator aborts.

**Affected Versions** - Introduced by commit `6409f34d637a34a1c643632aa849371ec8b3b5a8` (“Added fontFamily to the Image class of Magick++”, 2015-08-01, blame line 313). - Present in all releases that include that commit, at least ImageMagick 7.0.1-…
