How to fix?

Upgrade Debian:unstable libonig to version 6.9.4-1 or higher.

NVD Description

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

An integer overflow in the search_in_range function in regexec.c in Oniguruma 6.x before 6.9.4_rc2 leads to an out-of-bounds read, in which the offset of this read is under the control of an attacker. (This only affects the 32-bit compiled version). Remote attackers can cause a denial-of-service or information disclosure, or possibly have unspecified other impact, via a crafted regular expression.
