EulerOS Virtualization 2.9.1 : krb5 (EulerOS-SA-2023-3086)

medium Nessus Plugin ID 188489

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

According to the versions of the krb5 packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

 - 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 Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected krb5 packages.
