How to fix?

There is no fixed version for RHEL:7 virtuoso-opensource.

NVD Description

Note: Versions mentioned in the description apply only to the upstream virtuoso-opensource package and not the virtuoso-opensource package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
