CVE-2007-2798 krb5 kadmind buffer overflow
Last modified: 2008-02-26 10:14:21 EST
MIT has reported another flaw to us, CVE-2007-2798:
The MIT krb5 Kerberos administration daemon (kadmind) is vulnerable to
a stack buffer overflow.
The kadmind code which performs the principal renaming operation
passes unchecked string arguments to a sprintf() call which has a
fixed-size stack buffer as its destination. These strings are the old
and new principal names passed to the rename operation. The attacker
needs to authenticate to kadmind to perform this attack, but no
administrative privileges are required because the vulnerable code
executes prior to privilege verification.
The attacker must be authenticated, therefore this issue is important impact on
Red Hat Enterprise Linux.

Support Can you please give me a status on the release for the fix. I need
rpm's for RHELWSV4 and RHELWSV3 ASAP
