CVE-2019-18218  (opens in a new tab)
CWE-787  (opens in a new tab)

How to fix?

Upgrade Debian:11 file to version 1:5.37-6 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream file package and not the file package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

cdf_read_property_info in cdf.c in file through 5.37 does not restrict the number of CDF_VECTOR elements, which allows a heap-based buffer overflow (4-byte out-of-bounds write).
