Description

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.
