Scientific Linux Security Update : samba on SL5.x i386/x86_64

High Nessus Plugin ID 60413

Synopsis

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

Description

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.
(CVE-2008-1105)

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.

Solution

Update the affected packages.
