Description
===========
Multiple vulnerabilities have been discovered in PCRE2. Please review
the referenced CVE identifiers for details.
Impact
======
A remote attacker could possibly execute arbitrary code with the
privileges of the process, cause a Denial of Service condition, or have
other unspecified impacts.
Workaround
==========
There is no known workaround at this time.
Resolution
