Synopsis
========
OpenSSL contains a vulnerability allowing execution of arbitrary code
or a Denial of Service.
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 >= 0.9.8f < 0.9.8f
Description
===========
Andy Polyakov reported a vulnerability in the OpenSSL toolkit, that is
caused due to an unspecified off-by-one error within the DTLS
implementation.
Impact
======
A remote attacker could exploit this issue to execute arbitrary code or
cause a Denial of Service. Only clients and servers explicitly using
DTLS are affected, systems using SSL and TLS are not.
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-0.9.8f"
References
==========
