Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The BEGIN regular expression in the awk script detector in magic/Magdir/commands in file before 5.15 uses multiple wildcards with unlimited repetitions, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted ASCII file that triggers a large amount of backtracking, as demonstrated via a file with many newline characters.

Mitigation

Update the affected package php.

Vulnerable software versions

Slackware Linux: 14.0 - 14.1
