Technical details

A stack-based buffer overflow (CWE-121) exists in ImageMagick's msl.c component. The vulnerability is triggered when the software processes a long value for a specific attribute within a Magick Scripting Language (MSL) file, which overflows a fixed-size stack buffer. This leads to an out-of-bounds write and subsequent memory corruption. An attacker can exploit this over a network without authentication, though the attack complexity is rated as high. Successful exploitation can result in a crash (denial of service) or the leakage of sensitive information from memory. The issue is resolved in versions 7.1.2-15 and 6.9.13-40.
