CVE-2008-4827

TITLE

AddTab Multiple heap overflow vulnerabilities in methods

DESCRIPTION

Multiple heap-based buffer overflows in the AddTab method in the (1) Tab and (2) CTab ActiveX controls in c1sizer.ocx and the (3) TabOne ActiveX control in sizerone.ocx in ComponentOne SizerOne 8.0.20081.140, as used in ComponentOne Studio for ActiveX 2008, TSC2 Help Desk 4.1.8, SAP GUI 6.40 Patch 29 and 7.10, and possibly other products, allow remote attackers to execute arbitrary code by adding many tabs, or adding tabs with long tab captions. The SizerOne ActiveX control used in products by multiple vendors is prone to a buffer-overflow vulnerability because it fails to properly bounds-check user-supplied data before copying it into an insufficiently sized memory buffer. An attacker can exploit this issue to execute arbitrary code within the context of the application that uses the ActiveX control (typically Internet Explorer). Failed exploit attempts will result in denial-of-service conditions. ====================================================================== 2) Severity Rating: Highly critical Impact: System compromise Where: Remote ====================================================================== 3) Vendor's Description of Software "SAP GUI is SAP's universal client for accessing SAP functionality in SAP applications such as - SAP ERP, SAP Business Suite (SAP CRM, SAP SCM and SAP PLM), SAP Business Intelligence and so on. SAP GUI functions like a browser. It gets information from the SAP server like what, where, when and how, to display contents in its window.". Users can also set the kill-bit manually by following the procedure explained in SAP note 1092631. ====================================================================== Secunia Research 07/01/2009 - ComponentOne SizerOne ActiveX Control Buffer Overflow - ====================================================================== Table of Contents Affected Software....................................................1 Severity.............................................................2 Vendor's Description of Software.....................................3 Description of Vulnerability.........................................4 Solution.............................................................5 Time Table...........................................................6 Credits..............................................................7 References...........................................................8 About Secunia........................................................9 Verification........................................................10 ====================================================================== 1) Affected Software * ComponentOne SizerOne 8.0.20081.140 NOTE: Other versions may also be affected. ====================================================================== 2) Severity Rating: Highly critical Impact: System compromise Where: Remote ====================================================================== 3) Vendor's Description of Software "ComponentOne SizerOne 8.0 is a four-in-one tool that includes two resizing controls to easily handle both simple and complex sizing. The tabbing control enables you to quickly create notebook-style and Microsoft Outlook-style tabs. And with the parsing control, you can automatically slice and dice strings." Product Link: http://www.componentone.com/SuperProducts/SizerOne/ ====================================================================== 4) Description of Vulnerability Secunia Research has discovered a vulnerability in ComponentOne SizerOne, which can be exploited by malicious people to potentially compromise a user's system. The vulnerability is caused by a boundary error in the included Tab ActiveX control (c1sizer.ocx) when copying tab captions. This can be exploited to cause a heap-based buffer overflow by e.g. adding tabs with overly long captions via the "AddTab()" method. Successful exploitation may allow execution of arbitrary code. ====================================================================== 5) Solution Update to version 8.0.20081.142 of the ActiveX control. ====================================================================== 6) Time Table 13/11/2008 - Vendor notified. 19/11/2008 - Vendor response. 25/11/2008 - Vendor informs that vulnerability has been fixed and offers to provide test version. 26/11/2008 - Copy of fixed test version requested. 01/12/2008 - Test version provided by the vendor. 02/12/2008 - Vendor informed that patch fixes vulnerability nicely. 02/12/2008 - Vendor informs that fix will be available within a week. 05/01/2008 - Status update requested. 05/01/2008 - Vendor informs that fix has been made available. 07/01/2009 - Public disclosure. ====================================================================== 7) Credits Discovered by Carsten Eiram, Secunia Research. ====================================================================== 8) References The Common Vulnerabilities and Exposures (CVE) project has assigned CVE-2008-4827 for the vulnerability. ====================================================================== 9) About Secunia Secunia offers vulnerability management solutions to corporate customers with verified and reliable vulnerability intelligence relevant to their specific system configuration: http://secunia.com/advisories/business_solutions/ Secunia also provides a publicly accessible and comprehensive advisory database as a service to the security community and private individuals, who are interested in or concerned about IT-security. http://secunia.com/advisories/ Secunia believes that it is important to support the community and to do active vulnerability research in order to aid improving the security and reliability of software in general: http://secunia.com/secunia_research/ Secunia regularly hires new skilled team members.
