Detail

Synopsis

Multiple vulnerabilities have been found in OpenSSL, the worst allowing remote attackers to decrypt TLS sessions.

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, the worst being a cross-protocol attack called DROWN that could lead to the decryption of TLS sessions. Please review the CVE identifiers referenced below for details.

Impact

A remote attacker could decrypt TLS sessions by using a server supporting SSLv2 and EXPORT cipher suites as a Bleichenbacher RSA padding oracle, cause a Denial of Service condition, obtain sensitive information from memory and (in rare circumstances)
recover RSA keys.

Workaround

A workaround for DROWN is disabling the SSLv2 protocol on all SSL/TLS servers.

Resolution

All OpenSSL users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-1.0.2g-r2"

Please note that beginning with OpenSSL 1.0.2, in order to mitigate the DROWN attack, the OpenSSL project disables SSLv2 by default at build-time. As this change would cause severe issues with some Gentoo packages that depend on OpenSSL, Gentoo still ships OpenSSL with SSLv2
enabled at build-time. Note that this does not mean that you are still vulnerable to DROWN because the OpenSSL project has taken further precautions and applications would need to explicitly request SSLv2. We are working on a migration path to phase out SSLv2 that ensures that no user-facing issues occur. Please reference bug 576128 for further details on how this decision was made.
