SUSE SLES11 Security Update : openssl1 (SUSE-SU-2020:14511-1)

low Nessus Plugin ID 150531

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES11 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2020:14511-1 advisory.

 - The Raccoon attack exploits a flaw in the TLS specification which can lead to an attacker being able to compute the pre-master secret in connections which have used a Diffie-Hellman (DH) based ciphersuite. In such a case this would result in the attacker being able to eavesdrop on all encrypted communications sent over that TLS connection. The attack can only be exploited if an implementation re-uses a DH secret across multiple TLS connections. Note that this issue only impacts DH ciphersuites and not ECDH ciphersuites.
 This issue affects OpenSSL 1.0.2 which is out of support and no longer receiving public updates. OpenSSL 1.1.1 is not vulnerable to this issue. Fixed in OpenSSL 1.0.2w (Affected 1.0.2-1.0.2v). (CVE-2020-1968)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
