CVE-2026-109261ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 Memory Leak in GIF Encoder
Low 3.7
In plain English
A low-severity memory leak in ImageMagick from ImageMagick. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 37% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains a memory leak in the GIF encoder because allocated memory is not released when color quantization fails during encoding. Attackers can supply images whose GIF conversion causes quantization to fail, leaking memory with each attempt and degrading availability.
