Multiple Kerberos Implementations Authentication Context Stack Overflow Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of MIT Kerberos. Authentication is not required to exploit this vulnerability. The specific flaw exists in the svcauthgssvalidate function. By sending a large authentication context over RPC, a stack...

MIT Kerberos 5: Multiple vulnerabilities

Background MIT Kerberos 5 is a suite of applications that implement the Kerberos network protocol. kadmind is the MIT Kerberos 5 administration daemon. Description A stack buffer overflow CVE-2007-3999 has been reported in svcauthgssvalidate of the RPC library of kadmind. Another vulnerability...

Mandrake Linux Security Advisory : krb5 (MDKSA-2007:174-1)

A stack-based buffer overflow vulnerability was discovered in the RPC library used by Kerberos' kadmind program by Tenable Network Security. A remote unauthenticated user who could access kadmind would be able to trigger the flaw and cause it to crash CVE-2007-3999. This issue is only applicable ...
