New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 5.9

An input validation flaw was found in the way Samba handled Any Batched (AndX) requests. A remote, unauthenticated attacker could send a specially crafted SMB packet to the Samba server, possibly resulting in arbitrary code execution with the privileges of the Samba server (root). (CVE-2012-0870)
Red Hat would like to thank the Samba team for reporting this issue.
Upstream acknowledges Andy Davis of NGS Secure as the original reporter.
