NVD Description

Note: Versions mentioned in the description apply to the upstream pcre3 package. See Remediation section below for Debian:9 relevant versions.

PCRE before 8.38 mishandles the interaction of lookbehind assertions and mutually recursive subpatterns, which allows remote attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.

Remediation

Upgrade Debian:9 pcre3 to version 2:8.38-1 or higher.
