Detail
| Problem Description: Updated samba packages that fix one security issue are now available for Red Hat Enterprise Linux 4 and 5, and Red Hat Enterprise Linux 5.3 Long Life, and 5.6 Extended Update Support. The Red Hat Security Response Team has rated this update as having critical 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. 2. Relevant releases/architectures: RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux EUS (v. 5.6 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Long Life (v. 5.3 server) - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 3. Description: Samba is a suite of programs used by machines to share files, printers, and other information. An input validation flaw was found in the way Samba handled Any Batched (AndX) requests. A remote, unauthenticated attacker could send a specially-crafted SMB packet to the Samba server, possibly resulting in arbitrary code execution with the privileges of the Samba server (root). (CVE-2012-0870) Red Hat would like to thank the Samba team for reporting this issue. Upstream acknowledges Andy Davis of NGS Secure as the original reporter. Users of Samba are advised to upgrade to these updated packages, which contain a backported patch to resolve this issue. 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/knowledge/articles/11258 5. Bugs fixed (http://bugzilla.redhat.com/): 795509 - CVE-2012-0870 samba: Any Batched ("AndX") request processing infinite recursion and heap-based buffer overflow |
