==================================================================== Red Hat Security Advisory Synopsis: Important: samba3x security update Advisory ID: RHSA-2011:0306-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2011:0306.html Issue date: 2011-03-01 CVE Names: CVE-2011-0719 ==================================================================== 1. Summary: Updated samba3x packages that fix one security issue are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having important 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 Desktop (v. 5 client) - i386, x86_64 3. Description: Samba is a suite of programs used by machines to share files, printers, and other information. A flaw was found in the way Samba handled file descriptors. If an attacker were able to open a large number of file descriptors on the Samba server, they could flip certain stack bits to "1" values, resulting in the Samba server (smbd) crashing. (CVE-2011-0719) Red Hat would like to thank the Samba team for reporting this issue. 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.
