Last modified Jun 17, 2026

CVE-2013-7345 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 2.98% chance of exploitation in the next 30 days.
