CWE-20  (opens in a new tab)

How to fix?

Upgrade Debian:10 perl to version 5.22.1-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream perl package and not the perl package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

The (1) S_reghop3, (2) S_reghop4, and (3) S_reghopmaybe3 functions in regexec.c in Perl before 5.24.0 allow context-dependent attackers to cause a denial of service (infinite loop) via crafted utf-8 data, as demonstrated by "a\x80."
