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 is different from CVSS.

VPR Score: 6.7

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

Security Fix(es) :

- A race condition was found in samba server. A malicious samba client could use this flaw to access files and directories in areas of the server file system not exported under the share definitions. (CVE-2017-2619)

- It was found that samba did not enforce 'SMB signing' when certain configuration options were enabled. A remote attacker could launch a man- in-the-middle attack and retrieve information in plain-text. (CVE-2017-12150)

- An information leak flaw was found in the way SMB1 protocol was implemented by Samba. A malicious client could use this flaw to dump server memory contents to a file on the samba share or to a shared printer, though the exact area of server memory cannot be controlled by the attacker. (CVE-2017-12163)

Solution

Update the affected packages.
