The remote Scientific Linux host is missing one or more security updates.


A heap-based buffer overflow flaw was found in the way Samba clients handle over-sized packets. If a client connected to a malicious Samba server, it was possible to execute arbitrary code as the Samba client user. It was also possible for a remote user to send a specially crafted print request to a Samba server that could result in the server executing the vulnerable client code, resulting in arbitrary code execution with the permissions of the Samba server.

This update also addresses two issues which prevented Samba from joining certain Windows domains with tightened security policies, and prevented certain signed SMB content from working as expected :

- when some Windows® 2000-based domain controllers were set to use mandatory signing, Samba clients would drop the connection because of an error when generating signatures. This presented as a 'Server packet had invalid SMB signature' error to the Samba client. This update corrects the signature generation error.

- Samba servers using the 'net ads join' command to connect to a Windows Server® 2003-based domain would fail with 'failed to get schannel session key from server' and 'NT_STATUS_ACCESS_DENIED' errors. This update correctly binds to the NETLOGON share, allowing Samba servers to connect to the domain properly.
