medium Nessus Plugin ID 143578

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of openssl installed on the remote host is prior to 1.0.2k-19. The version of openssl11 installed on the remote host is prior to 1.1.1c-15. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2020-1573 advisory.

 A null pointer dereference flaw was found in openssl. A remote attacker, able to control the arguments of the GENERAL_NAME_cmp function, could cause the application, compiled with openssl to crash resulting in a denial of service. The highest threat from this vulnerability is to system availability. (CVE-2020-1971)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update openssl' to update your system.
 Run 'yum update openssl11' to update your system.
