Package : imagemagick Version : 8:6.9.11.60+dfsg-1.3+deb11u8 CVE ID : CVE-2025-65955 CVE-2025-66628 CVE-2025-68469 CVE-2025-68618 CVE-2025-68950 CVE-2025-69204 Debian Bug : 1122584 1122827

Multiple vulnerabilities were fixed in imagemagick a popular image processing suite.

CVE-2025-65955

A vulnerability was found 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

CVE-2025-66628

The TIM (PSX TIM) image parser contains a critical integer overflow vulnerability in its ReadTIMImage function (coders/tim.c). The code reads width and height (16-bit values) from the file header and calculates image_size = 2 * width * height without checking for overflow. On 32-bit systems (or where size_t is 32-bit), this calculation can overflow if width and height are large (e.g., 65535), wrapping around to a small value

CVE-2025-68469

ImageMagick crashes when processing a crafted TIFF file

CVE-2025-68618

Magick's failure to limit the depth of SVG file reads caused a DoS attack.

CVE-2025-68950

Magick's failure to limit MVG mutual references forming a loop

CVE-2025-69204

Converting a malicious MVG file to SVG caused an integer overflow.

For Debian 11 bullseye, these problems have been fixed in version 8:6.9.11.60+dfsg-1.3+deb11u8.

We recommend that you upgrade your imagemagick packages.
