Multiple vulnerabilities in OpenSSL might allow remote attackers to conduct multiple attacks, including the injection of arbitrary data into encrypted byte streams.
|Package||dev-libs/openssl on all architectures|
|Affected versions||< 0.9.8l-r2|
|Unaffected versions||>= 0.9.8l-r2|
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.
Multiple vulnerabilities have been reported in OpenSSL:
A remote unauthenticated attacker, acting as a Man in the Middle, could inject arbitrary plain text into a TLS session, possibly leading to the ability to send requests as if authenticated as the victim. A remote attacker could furthermore send specially crafted DTLS packages to a service using OpenSSL for DTLS support, possibly resulting in a Denial of Service. Also, a remote attacker might be able to create rogue certificates, facilitated by a MD2 collision. NOTE: The amount of computation needed for this attack is still very large.
There is no known workaround at this time.
All OpenSSL users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/openssl-0.9.8l-r2"
