ImageMagick before 7.1.2-30 and 6.9.13-55 contains a time-of-check-time-of-use (TOCTOU) vulnerability in the video decoder that allows attackers to bypass path policy write restrictions via symlink swaps. An attacker can replace a symlink between policy validation (check-time) and the file write operation (use-time) to write to policy-denied locations.
A flaw was found in ImageMagick. This time-of-check-time-of-use (TOCTOU) vulnerability, involving a symlink race in the video decoder, allows a local attacker with low privileges to bypass path policy write restrictions. By replacing a symbolic link between the security check and the actual file write operation, an attacker can write to locations that should otherwise be protected, potentially leading to unauthorized file modification.
