CVE-2013-1416 Open this link in a new tabHow to fix?
Upgrade Debian:10 krb5 to version 1.10.1+dfsg-5 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream krb5 package and not the krb5 package as distributed by Debian.
See How to fix? for Debian:10 relevant fixed versions and status.
The prep_reprocess_req function in do_tgs_req.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.10.5 does not properly perform service-principal realm referral, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted TGS-REQ request.
