| Description: | Samba is an open-source implementation of the Server Message Block (SMB) orCommon Internet File System (CIFS) protocol, which allows PC-compatiblemachines to share files, printers, and other information.A heap-based buffer overflow flaw was found in Samba's NetBIOS messageblock daemon (nmbd). An attacker on the local network could use this flawto send specially crafted packets that, when processed by nmbd, couldpossibly lead to arbitrary code execution with root privileges.(CVE-2014-3560)This update also fixes the following bug:* Prior to this update, Samba incorrectly used the O_TRUNC flag when usingthe open(2) system call to access the contents of a file that was alreadyopened by a different process, causing the file's previous contents to beremoved. With this update, the O_TRUNC flag is no longer used in the abovescenario, and file corruption no longer occurs. (BZ#1115490)All Samba users are advised to upgrade to these updated packages, whichcontain backported patches to correct these issues. After installing thisupdate, the smb service will be restarted automatically. |
