Summary

Samba is a suite of programs used by machines to share files, printers, and other information.
A missing array boundary checking flaw was found in the way Samba parsed the binary representation of Windows security identifiers (SIDs). A malicious client could send a specially-crafted SMB request to the Samba server, resulting in arbitrary code execution with the privileges of the Samba server (smbd). (CVE-2010-3069)
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.
