Detail
The push_ascii function in smbd in Samba 3.6.x before 3.6.24, 4.0.x before 4.0.19, and 4.1.x before 4.1.9 allows remote authenticated users to cause a denial of service (memory corruption and daemon crash) via an attempt to read a Unicode pathname without specifying use of Unicode, leading to a character-set conversion failure that triggers an invalid pointer dereference. |

Title: | DEPRECATED: RHSA-2014:0867: samba security update (Moderate) | ||
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 denial of service flaw was found in the way the sys_recvfile() function of nmbd, the NetBIOS message block daemon, processed non-blocking sockets. An attacker could send a specially crafted packet that, when processed, would cause nmbd to enter an infinite loop and consume an excessive amount of CPU time. (CVE-2014-0244) A flaw was found in the way Samba created responses for certain authenticated client requests when a shadow-copy VFS module was enabled. An attacker able to send an authenticated request could use this flaw to disclose limited portions of memory per each request. (CVE-2014-0178) It was discovered that smbd, the Samba file server daemon, did not properly handle certain files that were stored on the disk and used a valid Unicode character in the file name. An attacker able to send an authenticated non-Unicode request that attempted to read such a file could cause smbd to crash. (CVE-2014-3493) Red Hat would like to thank Daniel Berteaud of FIREWALL-SERVICES SARL for reporting CVE-2014-0244, and the Samba project for reporting CVE-2014-0178 and CVE-2014-3493. The Samba project acknowledges Christof Schmitt as the original reporter of CVE-2014-0178, and Simon Arlott as the original reporter of CVE-2014-3493. All Samba users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the smb service will be restarted automatically. | ||
