CVE-2012-1182

Status Candidate

Overview

The RPC code generator in Samba 3.x before 3.4.16, 3.5.x before 3.5.14, and 3.6.x before 3.6.4 does not implement validation of an array length in a manner consistent with validation of array memory allocation, which allows remote attackers to execute arbitrary code via a crafted RPC call.

Red Hat Security Advisory 2013-0515-02
Posted Feb 21, 2013

Red Hat Security Advisory 2013-0515-02 - The openchange packages provide libraries to access Microsoft Exchange servers using native protocols. Evolution-MAPI uses these libraries to integrate the Evolution PIM application with Microsoft Exchange servers. A flaw was found in the Samba suite's Perl-based DCE/RPC IDL compiler. As OpenChange uses code generated by PIDL, this could have resulted in buffer overflows in the way OpenChange handles RPC calls. With this update, the code has been generated with an updated version of PIDL to correct this issue. The openchange packages have been upgraded to upstream version 1.0, which provides a number of bug fixes and enhancements over the previous version, including support for the rebased samba4 packages and several API changes.

Red Hat Security Advisory 2013-0506-02 - Samba is an open-source implementation of the Server Message Block or Common Internet File System protocol, which allows PC-compatible machines to share files, printers, and other information. A flaw was found in the Samba suite's Perl-based DCE/RPC IDL compiler, used to generate code to handle RPC calls. This could result in code generated by the PIDL compiler to not sufficiently protect against buffer overflows. The samba4 packages have been upgraded to upstream version 4.0.0, which provides a number of bug fixes and enhancements over the previous version. In particular, improved interoperability with Active Directory domains. SSSD now uses the libndr-krb5pac library to parse the Privilege Attribute Certificate issued by an AD Key Distribution Center .

Samba SetInformationPolicy AuditEventsInfo Heap Overflow
Posted Sep 28, 2012
Authored by unknown, Blasty, sinn3r, juan vazquez | Site metasploit.com

This Metasploit module triggers a vulnerability in the LSA RPC service of the Samba daemon because of an error on the PIDL auto-generated code. Making a specially crafted call to SetInformationPolicy to set a PolicyAuditEventsInformation allows to trigger a heap overflow and finally execute arbitrary code with root privileges. The module uses brute force to guess the system() address and redirect flow there in order to bypass NX. The start and stop addresses for brute forcing have been calculated empirically. On the other hand the module provides the StartBrute and StopBrute which allow the user to configure his own addresses.
