CVE-2010-4022 Open this link in a new tabHow to fix?
Upgrade Debian:10 krb5 to version 1.8.3+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 do_standalone function in the MIT krb5 KDC database propagation daemon (kpropd) in Kerberos 1.7, 1.8, and 1.9, when running in standalone mode, does not properly handle when a worker child process "exits abnormally," which allows remote attackers to cause a denial of service (listening process termination, no new connections, and lack of updates in slave KVC) via unspecified vectors.
