Medium Nessus Plugin ID 118847
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201811-03 (OpenSSL: Denial of Service)
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.
SolutionAll OpenSSL users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/openssl-1.0.2o-r6'
