gdb security update (RHSA-2005-801)

Original Release Date: January 16, 2006
Last Revised: November 8, 2006
Number: ASA-2006-015
Risk Level: Low
Advisory Version: 4.0
Advisory Status: Interim

1. Overview:

GDB, the GNU debugger, allows debugging of programs written in C, C++, and other languages by executing them in a controlled fashion, then printing their data.

Several integer overflow bugs were found in gdb. If a user is tricked into processing a specially crafted executable file, it may allow the execution of arbitrary code as the user running gdb. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1704 to this issue.

A bug was found in the way gdb loads .gdbinit files. When a user executes gdb, the local directory is searched for a .gdbinit file which is then loaded. It is possible for a local user to execute arbitrary commands as the user running gdb by placing a malicious .gdbinit file in a location where gdb may be run. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1705 to this issue.

Several Avaya System products utilize gdb, however only Avaya services personnel have access to gdb, therefore lowering the risk of exploitation.

More information about these vulnerabilities can be found in the security advisory issued by RedHat Linux:

Recommended Actions:
For all system products which use vulnerable versions of gdb, Avaya recommends that customers restrict local and network access to the server.

3. Avaya Software-Only Products

Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.

In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendors guidance:

4. Software-Only Products:

Product: Affected Version(s): Risk Level: Actions:
Avaya Interactive Response(IR) All None Depending on the Operating System provided by customers, the affected packages may be installed on the underlying Operating System supporting the IR application. The IR application does not require the software described in this advisory.
CVLAN all? Low See recommended actions below.
Avaya Integrated Management Suite(IMS) All None Depending on the Operating System provided by customers, the affected packages may be installed on the underlying Operating System supporting the IMS application. The IMS application does not require the software described in this advisory.
