CVE-2013-7345

file < 5.15 - Denial of Service via Crafted ASCII File with Excessive Newlines

Title source: llm
STIX 2.1

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.
