EulerOS 2.0 SP2 : openssl110f (EulerOS-SA-2018-1306)

Medium Nessus Plugin ID 117749

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the openssl110f packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- 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.

Solution

Update the affected openssl110f packages.
