http://security.gentoo.org/

Severity:	normal
Title:	OpenSSL: Multiple Vulnerabilities
Date:	11/01/2022
Bugs:	#878269
ID:	202211-01

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	Architecture(s)
dev-libs/openssl	< 3.0.7	>= 3.0.7	All supported architectures

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 ">=dev-libs/openssl-3.0.7"
