I. Description CA Unicenter DSM ITRM Legends is an ActiveX control that is included with multiple CA products. This ActiveX control, which is provided by gui_cm_ctrls.ocx, contains an integer overflow vulnerability. According to the vendor, the following products are affected: BrightStor ARCServe Backup for Laptops and Desktops r11.5 CA Desktop Management Suite r11.2 C2 CA Desktop Management Suite r11.2 C1 CA Desktop Management Suite r11.2a CA Desktop Management Suite r11.2 CA Desktop Management Suite r11.1 (GA, a, C1) Unicenter Desktop Management Bundle r11.2 C2 Unicenter Desktop Management Bundle r11.2 C1 Unicenter Desktop Management Bundle r11.2a Unicenter Desktop Management Bundle r11.2 Unicenter Desktop Management Bundle r11.1 (GA, a, C1) Unicenter Asset Management r11.2 C2 Unicenter Asset Management r11.2 C1 Unicenter Asset Management r11.2a Unicenter Asset Management r11.2 Unicenter Asset Management r11.1 (GA, a, C1) Unicenter Software Delivery r11.2 C2 Unicenter Software Delivery r11.2 C1 Unicenter Software Delivery r11.2a Unicenter Software Delivery r11.2 Unicenter Software Delivery r11.1 (GA, a, C1) Unicenter Remote Control r11.2 C2 Unicenter Remote Control r11.2 C1 Unicenter Remote Control r11.2a Unicenter Remote Control r11.2 Unicenter Remote Control r11.1 (GA, a, C1) CA Desktop and Server Management r11.2 C2 CA Desktop and Server Management r11.2 C1 CA Desktop and Server Management r11.2a CA Desktop and Server Management r11.2 CA Desktop and Server Management r11.1 (GA, a, C1) II. Impact By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code with the privileges of the user. III. Solution Apply an update Apply updates, as specified in the CA Security Notice. Disable the Creative Software AutoUpdate ActiveX control in Internet Explorer The vulnerable ActiveX control can be disabled in Internet Explorer by setting the kill bit for the following CLSID: {E6239EB3-E0B0-46DA-A215-CFA9B3B740C5} More information about how to set the kill bit is available in Microsoft Support Document 240797. Alternatively, the following text can be saved as a .REG file and imported to set the kill bit for this control: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\ {E6239EB3-E0B0-46DA-A215-CFA9B3B740C5}] "Compatibility Flags"=dword:00000400 Disable ActiveX Disabling ActiveX controls in the Internet Zone (or any zone used by an attacker) appears to prevent exploitation of this and other ActiveX vulnerabilities. Instructions for disabling ActiveX in the Internet Zone can be found in the "Securing Your Web Browser" document.
