Title: OpenSSL: Denial of Service (GLSA 201811-03)
A vulnerability in OpenSSL might allow remote attackers to cause a
Denial of Service condition.
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.
Vulnerable: < 1.0.2o-r6
Unaffected: >= 1.0.2o-r6
Architectures: All supported architectures
It was discovered that OpenSSL allow malicious servers to send very
large primes to a client during DH(E) based TLS handshakes.
A remote attacker, by sending large prime to client during DH(E) TLS
handshake, could possibly cause a Denial of Service condition.
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-1.0.2o-r6"
