|Bugzilla:||664009: CVE-2010-4022 krb5: kpropd unexpected termination on invalid input (MITKRB5-SA-2011-001)|
The MITRE CVE dictionary describes this issue as:
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.
This issue did not affect the versions of krb5 as shipped with Red Hat Enterprise Linux 4 or 5 as the flaw was introduced in a later version of MIT krb5 (1.7).
