CBL Mariner 2.0 Security Update: heimdal / krb5 / samba (CVE-2022-42898)

high Nessus Plugin ID 172769

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of heimdal / krb5 / samba installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-42898 advisory.

 - PAC parsing in MIT Kerberos 5 (aka krb5) before 1.19.4 and 1.20.x before 1.20.1 has integer overflows that May lead to remote code execution (in KDC, kadmind, or a GSS or Kerberos application server) on 32-bit platforms (which have a resultant heap-based buffer overflow), and cause a denial of service on other platforms. This occurs in krb5_pac_parse in lib/krb5/krb/pac.c. Heimdal before 7.7.1 has a similar bug.
 (CVE-2022-42898)

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.
