Description

The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:14597-1 advisory.

- A flaw was found in OpenLDAP. This flaw allows an attacker who can send a malicious packet to be processed by OpenLDAPs 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 this issue but has instead relied only on the application's self-reported version number.
