Detail
| Problem Description: Updated samba3x and samba packages that fix two security issues are now available for Red Hat Enterprise Linux 5 and 6 respectively. The Red Hat Security Response Team has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. 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) 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-2014-3493. The Samba project acknowledges 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. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 1097815 - CVE-2014-0244 samba: nmbd denial of service 1108748 - CVE-2014-3493 samba: smbd unicode path names denial of service |

| 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. | ||
