How to fix?

Upgrade Debian:10 fribidi to version 1.0.5-3.1+deb10u2 or higher.

NVD Description

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

A heap-based buffer overflow flaw was found in the Fribidi package and affects the fribidi_cap_rtl_to_unicode() function of the fribidi-char-sets-cap-rtl.c file. This flaw allows an attacker to pass a specially crafted file to the Fribidi application with the '--caprtl' option, leading to a crash and causing a denial of service.
