NVD Description

Note: Versions mentioned in the description apply only to the upstream file-libs package and not the file-libs package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2018.03 relevant fixed versions and status.

file before 5.19 does not properly restrict the amount of data read during a regex search, which allows remote attackers to cause a denial of service (CPU consumption) via a crafted file that triggers backtracking during processing of an awk rule. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-7345.
