Scientific Linux Security Update : samba and samba3x on SL5.x, SL6.x i386/x86_64 (20131210)

high Nessus Plugin ID 71341

Language:

Synopsis

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

Description

A heap-based buffer overflow flaw was found in the DCE-RPC client code in Samba. A specially crafted DCE-RPC packet could cause various Samba programs to crash or, possibly, execute arbitrary code when parsed. A malicious or compromised Active Directory Domain Controller could use this flaw to compromise the winbindd daemon running with root privileges. (CVE-2013-4408)

A flaw was found in the way Samba performed ACL checks on alternate file and directory data streams. An attacker able to access a CIFS share with alternate stream support enabled could access alternate data streams regardless of the underlying file or directory ACL permissions. (CVE-2013-4475)

After installing this update, the smb service will be restarted automatically.

Solution

Update the affected packages.
