Security Bulletin
Summary
An attacker could gain privileged access to IBM Storwize V7000 Unified system
by exploiting a vulnerability in Samba.
Vulnerability Details
CVE ID: CVE-2013-4408 and CVE-2012-6105
DESCRIPTION:
This issue affects only those IBM Storwize V7000 Unified systems that use
Active Directory server for authentication. Configuration with other
authentication server types are not affected by this issue.
IBM Storwize V7000 Unified includes a version of Samba that does not check
correctly for buffer overflows in winbindd. This enables remote Active
Directory servers to execute arbitrary code in the affected Samba and
potentially allows privileged access to the IBM Storwize V7000 Unified system
which could potentially result in system unavailability or unauthorized
disclosures if access is not otherwise restricted.
Samba is used on the IBM Storwize V7000 Unified system to enable file
management and authentication services for Microsoft Windows environments.
