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.

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:
