Amazon Linux 2 : openssl (ALAS-2022-1831)

critical Nessus Plugin ID 163919

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-24. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2022-1831 advisory.

 A flaw was found in OpenSSL. The issue in CVE-2022-1292 did not find other places in the `c_rehash` script where it possibly passed the file names of certificates being hashed to a command executed through the shell. Some operating systems distribute this script in a manner where it is automatically executed. On these operating systems, this flaw allows an attacker to execute arbitrary commands with the privileges of the script. (CVE-2022-2068)

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.
