Description Josh Bressers 2006-07-06 18:23:59 UTC 
Samba denial of service

Upstream alerted us to a denial of service bug in Samba.

Here is the description from the mail:

"""
We've got a small anonymous DoS against Samba 3.0.1 - 3.0.22
inclusive.  The bug is caused by continually increasing
the size of an array which maintains state information about
the number of active share connections.  The result is that
an attacker could cause a single smbd to bloat exhausting
the memory on a server.
"""


This issue also affects RHEL3
This issue also affects RHEL2.1
