CVE-2013-7345

MEDIUM 5.0EPSS 3.04%

Does this matter?

Lower severity and a low EPSS score (3.04%). Track it; it rarely justifies an emergency change on its own.

Description

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.
