Scientific Linux Security Update : samba on SL3.x, SL4.x, SL5.x i386/x86_64

Synopsis :

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

Description :

NOTE: This errata went out 2010-09-15, but this email was not sent.

A missing array boundary checking flaw was found in the way Samba
parsed the binary representation of Windows security identifiers
(SIDs). A malicious client could send a specially crafted SMB request
to the Samba server, resulting in arbitrary code execution with the
privileges of the Samba server (smbd). (CVE-2010-3069)

For Scientific Linux 4, this update also fixes the following bug :

- Previously, the restorecon utility was required during
the installationof the samba-common package. As a
result, attempting to update sambawithout this utility
installed may have failed with the following error :

/var/tmp/rpm-tmp.[xxxxx]: line 7: restorecon: command not found

With this update, the utility is only used when it is already present
on the system, and the package is now always updated as expected.
(BZ#629602)

After installing this update, the smb service will be restarted
automatically.
