Synopsis
========

Multiple vulnerabilities have been found in PCRE2, the worst of which

PCRE2 is a project based on PCRE (Perl Compatible Regular Expressions)
which has a new and revised API.

Affected packages

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
