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

-------------------------------------------------------------------

1 dev-libs/openssl < 1.0.0e >= 1.0.0e

 

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.
