Denial of Service Vulnerability in awk Script Detector

CVE-2013-7345 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:N/A:P

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.
