Xerox Security Bulletin XRX11-002 (PDF 92K)

A vulnerability documented in CVE-2010-2063 exists that, if exploited, could allow remote attackers to execute arbitrary code via specially crafted fields in a Service Message Block (SMB) packet. This could occur with buffer overflows in the Samba third-party code that handles file and printer sharing services for SMB clients (including Xerox MFD devices). If successful, an attacker could make unauthorized changes to the system configuration; however, customer and user passwords are not exposed. This vulnerability affects only the printer sharing services.
