Amazon Linux 2 : openldap (ALAS-2022-1770)

high Nessus Plugin ID 159556

Synopsis

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

Description

The version of openldap installed on the remote host is prior to 2.4.44-23. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1770 advisory.

- A flaw was found in OpenLDAP. This flaw allows an attacker who can send a malicious packet to be processed by OpenLDAP's slapd server, to trigger an assertion failure. The highest threat from this vulnerability is to system availability. (CVE-2020-25709)

- A flaw was found in OpenLDAP in versions before 2.4.56. This flaw allows an attacker who sends a malicious packet processed by OpenLDAP to force a failed assertion in csnNormalize23(). The highest threat from this vulnerability is to system availability. (CVE-2020-25710)

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

Solution

Run 'yum update openldap' to update your system.
