Zero Day Initiative Advisory 12-134
Posted Aug 3, 2012
Authored by Tipping Point | Site zerodayinitiative.com

Zero Day Initiative Advisory 12-134 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of IBM Lotus Quickr. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the QP2.cab ActiveX control. When passing a long string argument to the Attachment_Times or Import_Times parameters during the control's instantiation it is possible to overflow a stack buffer causing memory corruption. This can be leveraged by an attacker to execute code under the context of the user running the browser.
