Detail

The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.6.x through 1.9, when an LDAP backend is used, allows remote attackers to cause a denial of service (NULL pointer dereference or buffer over-read, and daemon crash) via a crafted principal name.

Title: USN-1062-1 -- krb5 vulnerabilities
Description: Keiichi Mori discovered that the MIT krb5 KDC database propagation daemon is vulnerable to a denial of service attack due to improper logic when a worker child process exited because of invalid network input. This could only occur when kpropd is running in standalone mode; kpropd was not affected when running in incremental propagation mode or as an inetd server. This issue only affects Ubuntu 9.10, Ubuntu 10.04 LTS, and Ubuntu 10.10. Kevin Longfellow and others discovered that the MIT krb5 Key Distribution Center daemon is vulnerable to denial of service attacks when using an LDAP back end due to improper handling of network input

Id Description
70909 Kerberos KDC LDAP Backend Principal Name Handling DoS

Kerberos contains a flaw that may allow a remote denial of service. The issue is triggered when the Key Distribution Center improperly processes certain principal names which causes a NULL pointer dereference error, when an LDAP backend is used, allowing a remote attacker to cause a denial of service via a crafted request.
