How to fix?

Upgrade Debian:10 pcre3 to version 2:8.38-3.1 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:10. See How to fix? for Debian:10 relevant fixed versions and status.

The pcre_compile2 function in pcre_compile.c in PCRE 8.38 mishandles the /((?:F?+(?:^(?(R)a+&#34;){99}-))(?J)(?'R'(?'R'<((?'RR'(?'R'){97)?J)?J)(?'R'(?'R'){99|(:(?|(?'R')(\k'R')|((?'R')))H'R'R)(H'R))))))/ pattern and related patterns with named subgroups, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.
