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

All PCRE2 users should upgrade to the latest version:
