RHSA-2013:1805 - Important: samba4 security update
Synopsis
Important: samba4 security update
Type/Severity
Security Advisory Important
Topic
Updated samba4 packages that fix one security issue are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
Description
Samba is an open-source implementation of the Server Message Block (SMB) or Common Internet File System (CIFS) protocol, which allows PC-compatible machines to share files, printers, and other information.
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)
Red Hat would like to thank the Samba project for reporting this issue. Upstream acknowledges Stefan Metzmacher and Michael Adam of SerNet as the original reporters of this issue.
All users of Samba are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing this update, the smb service will be restarted automatically.
