Detail

Synopsis

Multiple vulnerabilities have been found in PCRE2, the worst of which may allow remote attackers to execute arbitrary code.

Background

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

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:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/libpcre2-10.30"

Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
