EulerOS Virtualization 2.5.3 : openssl (EulerOS-SA-2019-1267)

Medium Nessus Plugin ID 123735

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

- The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.1a (Affected 1.1.1). Fixed in OpenSSL 1.1.0j (Affected 1.1.0-1.1.0i). Fixed in OpenSSL 1.0.2q (Affected 1.0.2-1.0.2p).(CVE-2018-0734)

- A microprocessor side-channel vulnerability was found on SMT (e.g, Hyper-Threading) architectures. An attacker running a malicious process on the same core of the processor as the victim process can extract certain secret information.(CVE-2018-5407)

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 openssl packages.
