Description Vincent Danen 2010-06-07 22:02:08 UTC 
A memory corruption vulnerability exists in the chain_reply() function in Samba 3.3.12 and earlier.  3.4.x and later are not affected.  This flaw could allow a remote, unauthenticated attacker, to crash the samba server or, possibly, execute arbitrary code with the privileges of the samba server.

Acknowledgements:

Red Hat would like to thank the Samba team for responsibly reporting this issue. Upstream acknowledges Jun Mao as the original reporter.
