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 for each vulnerability from the CVE link(s) associated with each description below.
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.
Security Fix
- CVE-2012-1182
- A flaw in the Samba suite's Perl-based DCE/RPC IDL (PIDL) compiler, used to generate code to handle RPC calls, resulted in multiple buffer overflows in Samba. A remote, unauthenticated attacker could send a specially-crafted RPC request that would cause the Samba daemon (smbd) to crash or, possibly, execute arbitrary code with the privileges of the root user.
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.

Security Fix
- CVE-2012-2111
- A flaw was found in the way Samba handled certain Local Security Authority (LSA) Remote Procedure Calls (RPC). An authenticated user could use this flaw to issue an RPC call that would modify the privileges database on the Samba server, allowing them to steal the ownership of files and directories that are being shared by the Samba server, and create, delete, and modify user accounts, as well as other Samba server administration tasks.
Red Hat would like to thank the Samba project for reporting this issue. Upstream acknowledges Ivano Cristofolini as the original reporter.
