Description Tomas Hoger 2008-02-20 03:30:42 EST
MIT Kerberos Team reported following issue affecting RPC library server code
used by kadmin server:

A bug in the RPC library server code, used in the kadmin server,
causes an array overrun if too many file descriptors are opened.
Memory corruption can result.

Acknowledgements:

Red Hat would like to thank MIT and Jeff Altman of Secure Endpoints for reporting this issue.

Lifting embargo.
Comment 8 Tomas Hoger 2008-03-18 14:27:30 EDT
This issue only affected krb5 package in Red Hat Enterprise Linux 5 and Fedora.

However, default configuration did not affect default configuration.  This issue
only affected systems configured to use higher resource limit than default 1024
for 'open files'.
