The MIT Kerberos Development Team has discovered a number of vulnerabilities in the MIT Kerberos Version 5 software. The Common Vulnerabilities and Exposures project identifies the following vulnerabilities :
CAN-2004-0642 [VU#795632] A double-free error may allow unauthenticated remote attackers to execute arbitrary code on KDC or clients.
CAN-2004-0643 [VU#866472]
Several double-free errors may allow authenticated attackers to execute arbitrary code on Kerberos application servers.
CAN-2004-0644 [VU#550464]
A remotely exploitable denial of service vulnerability has been found in the KDC and libraries.
CAN-2004-0772 [VU#350792]
Several double-free errors may allow remote attackers to execute arbitrary code on the server. This does not affect the version in woody.
