Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2023:3398-1 advisory.

- lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (aka krb5) before 1.20.2 and 1.21.x before 1.21.1 frees an uninitialized pointer. A remote authenticated user can trigger a kadmind crash. This occurs because
_xdr_kadm5_principal_ent_rec does not validate the relationship between n_key_data and the key_data array count. (CVE-2023-36054)

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.
