EulerOS Virtualization 2.5.2 : openssl (EulerOS-SA-2019-1084)

medium Nessus Plugin ID 122706

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 RSA Key generation algorithm has been shown to be vulnerable to a cache timing side channel attack.
An attacker with sufficient access to mount cache timing attacks during the RSA key generation process could recover the private key. Fixed in OpenSSL 1.1.0i-dev (Affected 1.1.0-1.1.0h). Fixed in OpenSSL 1.0.2p-dev (Affected 1.0.2b-1.0.2o).(CVE-2018-0737)

- While parsing an IPAddressFamily extension in an X.509 certificate, it is possible to do a one-byte overread.
This would result in an incorrect text display of the certificate. This bug has been present since 2006 and is present in all versions of OpenSSL before 1.0.2m and 1.1.0g.(CVE-2017-3735)

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.
