Bugzilla: 928419: CVE-2013-0454 samba: the SMB2 server does not release unused shares


The MITRE CVE dictionary describes this issue as:

The SMB2 implementation in Samba 3.6.x before 3.6.6, as used on the IBM Storwize V7000 Unified 1.3 before and 1.4 before and possibly other products, does not properly enforce CIFS share attributes, which allows remote authenticated users to (1) write to a read-only share; (2) trigger data-integrity problems related to the oplock, locking, coherency, or leases attribute; or (3) have an unspecified impact by leveraging incorrect handling of the browseable or "hide unreadable" parameter.

Not vulnerable. This issue did not affect the versions of samba as shipped with Red Hat Enterprise Linux 5 as they did not provide support for SMB2. This issue did not affect the versions of samba3x and samba as shipped with Red Hat Enterprise Linux 6 as they ship newer versions that do not include the vulnerable code.
