The SMB service in EMC VNXe (VNXe3200 Operating Environment prior to 3.1.5.8711957 and VNXe3100/3150/3300 Operating Environment prior to 2.4.4.22638), VNX1 File OE before 7.1.80.3, VNX2 File OE before 8.1.9.155, and Celerra (all supported versions) does not prevent duplicate NTLM challenge-response nonces, which makes it easier for remote attackers to execute arbitrary code, or read or write to files, via a series of authentication requests, a related issue to CVE-2010-0231.

The SMB implementation in the Server service in Microsoft Windows 2000 SP4, Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista Gold, SP1, and SP2, Windows Server 2008 Gold, SP2, and R2, and Windows 7 does not use a sufficient source of entropy, which allows remote attackers to obtain access to files and other SMB resources via a large number of authentication requests, related to server-generated challenges, certain "duplicate values," and spoofing of an authentication token, aka "SMB NTLM Authentication Lack of Entropy Vulnerability."
