How to fix?

Upgrade Debian:10 pcre3 to version 2:8.35-7.2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream pcre3 package and not the pcre3 package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

The match function in pcre_exec.c in PCRE before 8.37 mishandles the /(?:((abcd))|(((?:(?:(?:(?:abc|(?:abcdef))))b)abcdefghi)abc)|((*ACCEPT)))/ pattern and related patterns involving (*ACCEPT), which allows remote attackers to obtain sensitive information from process memory or cause a denial of service (partially initialized memory and application crash) via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror, aka ZDI-CAN-2547.
