The remote CentOS Linux 9 host has packages installed that are affected by a vulnerability as referenced in the libldb-2.5.2-1.el9 build changelog.

  • A flaw was found in the Samba AD LDAP server. The AD DC database audit logging module can access LDAP message values freed by a preceding database module, resulting in a use-after-free issue. This issue is only possible when modifying certain privileged attributes, such as userAccountControl. (CVE-2022-32746)

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