CVE-2026-25968· NVD / CVE Program· CNA GitHub_M

ImageMagick has MSL attribute stack buffer overflow that leads to out of bounds write.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a stack buffer overflow occurs when processing the an attribute in msl.c. A long value overflows a fixed-size stack buffer, leading to memory corruption. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
