ID CVE-2012-1106
Summary The C handler plug-in in Automatic Bug Reporting Tool (ABRT), possibly 2.0.8 and earlier, does not properly set the group (GID) permissions on core dump files for setuid programs when the sysctl fs.suid_dumpable option is set to 2, which allows local users to obtain sensitive information.

CWE CWE-264
CAPEC
  • Accessing, Modifying or Executing Executable Files
    An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Blue Boxing
    This type of attack against older telephone switches and trunks has been around for decades. A tone is sent by an adversary to impersonate a supervisor signal which has the effect of rerouting or usurping command of the line. While the US infrastructure proper may not contain widespread vulnerabilities to this type of attack, many companies are connected globally through call centers and business process outsourcing. These international systems may be operated in countries which have not upgraded Telco infrastructure and so are vulnerable to Blue boxing. Blue boxing is a result of failure on the part of the system to enforce strong authorization for administrative functions. While the infrastructure is different than standard current applications like web applications, there are historical lessons to be learned to upgrade the access control for administrative functions.
  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.
  • Target Programs with Elevated Privileges
    This attack targets programs running with elevated privileges. The attacker would try to leverage a bug in the running program and get arbitrary code to execute with elevated privileges. For instance an attacker would look for programs that write to the system directories or registry keys (such as HKLM, which stores a number of critical Windows environment variables). These programs are typically running with elevated privileges and have usually not been designed with security in mind. Such programs are excellent exploit targets because they yield lots of power when they break. The malicious user try to execute its code at the same level as a privileged system call.
  • Manipulating Input to File System Calls
    An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

    description Updated abrt, libreport, btparser, and python-meh packages that fix two security issues and several bugs are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having low 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. ABRT (Automatic Bug Reporting Tool) is a tool to help users to detect defects in applications and to create a bug report with all the information needed by a maintainer to fix it. It uses a plug-in system to extend its functionality. libreport provides an API for reporting different problems in applications to different bug targets, such as Bugzilla, FTP, and Trac. The btparser utility is a backtrace parser and analyzer library, which works with backtraces produced by the GNU Project Debugger. It can parse a text file with a backtrace to a tree of C structures, allowing to analyze the threads and frames of the backtrace and process them. The python-meh package provides a python library for handling exceptions. If the C handler plug-in in ABRT was enabled (the abrt-addon-ccpp package installed and the abrt-ccpp service running), and the sysctl fs.suid_dumpable option was set to '2' (it is '0' by default), core dumps of set user ID (setuid) programs were created with insecure group ID permissions. This could allow local, unprivileged users to obtain sensitive information from the core dump files of setuid processes they would otherwise not be able to access. (CVE-2012-1106) ABRT did not allow users to easily search the collected crash information for sensitive data prior to submitting it. This could lead to users unintentionally exposing sensitive information via the submitted crash reports. This update adds functionality to search across all the collected data. Note that this fix does not apply to the default configuration, where reports are sent to Red Hat Customer Support. It only takes effect for users sending information to Red Hat Bugzilla. (CVE-2011-4088) Red Hat would like to thank Jan Iven for reporting CVE-2011-4088. These updated packages include numerous bug fixes. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.3 Technical Notes for information on the most significant of these changes. All users of abrt, libreport, btparser, and python-meh are advised to upgrade to these updated packages, which correct these issues.
