Synopsis
=======
Multiple vulnerabilities have been discovered in OpenSSL, the worst of
which could result in remote code execution.

Background
=========
OpenSSL is an Open Source toolkit implementing the Secure Sockets Layer
(SSL v2/v3) and Transport Layer Security (TLS v1) as well as a general
purpose cryptography library.

Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-libs/openssl < 3.0.7:0/3 >= 3.0.7:0/3

Description
==========
Multiple buffer overflows exist in OpenSSL's handling of TLS
certificates for client authentication.

Impact
=====
It is believed that, while unlikely, code execution is possible in
certain system configurations.

Workaround
=========
Users operating TLS servers may consider disabling TLS client
authentication, if it is being used, until fixes are applied.

Resolution
=========
All OpenSSL 3 users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">Þv-libs/openssl-3.0.7"
