Name of the Vulnerable Software and Affected Versions Intuit QuickBooks versions 2009 through 2012

Description The issue concerns the intu-help-qb handlers in HelpAsyncPluggableProtocol.dll. It might allow remote attackers to obtain sensitive information via a URI with a % (percent) character as its last or second-to-last character. This can happen when Internet Explorer is used and a certain "post-URL data" buffer contains a 0x0000 character but a buffer overflow does not occur.

Recommendations For Intuit QuickBooks versions 2009 through 2012, consider avoiding the use of Internet Explorer or restricting access to the HelpAsyncPluggableProtocol.dll handlers until a fix is available. As a temporary workaround, avoid using URIs with a % (percent) character as the last or second-to-last character.
