EulerOS 2.0 SP2 : openssl110f (EulerOS-SA-2018-1306)
Medium Nessus Plugin ID 117749
SynopsisThe remote EulerOS host is missing multiple security updates.
DescriptionAccording to the versions of the openssl110f packages installed, the
EulerOS installation on the remote host is affected by the following
- During key agreement in a TLS handshake using a DH(E)
based ciphersuite a malicious server can send a very
large prime value to the client. This will cause the
client to spend an unreasonably long period of time
generating a key for this prime resulting in a hang
until the client has finished. This could be exploited
in a Denial Of Service attack.(CVE-2017-0732)
- OpenSSL RSA key generation was found to be vulnerable
to cache side-channel attacks. An attacker with
sufficient access to mount cache timing attacks during
the RSA key generation process could recover parts of
the private key.(CVE-2018-0737)
Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
SolutionUpdate the affected openssl110f packages.
