Synopsis

Multiple vulnerabilities were found in OpenSSL, allowing for the execution of arbitrary code and other attacks.

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	< 1.0.0e	>= 1.0.0e	All supported architectures

Description

Multiple vulnerabilities have been discovered in OpenSSL. Please review the CVE identifiers referenced below for details.

Impact

A context-dependent attacker could cause a Denial of Service, possibly execute arbitrary code, bypass intended key requirements, force the downgrade to unintended ciphers, bypass the need for knowledge of shared secrets and successfully authenticate, bypass CRL validation, or obtain sensitive information in applications that use OpenSSL.

Workaround

There is no known workaround at this time.

Resolution

All OpenSSL users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-libs/openssl-1.0.0e"

NOTE: This is a legacy GLSA. Updates for all affected architectures are available since September 17, 2011. It is likely that your system is already no longer affected by most of these issues.
