Scientific Linux Security Update : samba on SL6.x i386/x86_64

Medium Nessus Plugin ID 103501

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
