Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SUSE15 host has packages installed that are affected by a vulnerability as referenced in the openSUSE-SU-2021:1182-1 advisory.

 - ec_verify in kdc/kdc_preauth_ec.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.18.4 and 1.19.x before 1.19.2 allows remote attackers to cause a NULL pointer dereference and daemon crash. This occurs because a return value is not properly managed in a certain situation. (CVE-2021-36222)

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.
