Description
Multiple buffer overflows in the (1) ActiveListen (Xlisten.dll) and (2) ActiveVoice (Xvoice.dll) speech controls, as used by Microsoft Internet Explorer 5.01, 6, and 7, allow remote attackers to execute arbitrary code via a crafted ActiveX object that triggers memory corruption, as demonstrated via the ModeName parameter to the FindEngine function in ACTIVEVOICEPROJECTLib.DirectSS.
Public exploits
Exploit or proof-of-concept code for this vulnerability is publicly available, which lowers the bar for attackers. Treat it as a reason to patch sooner.
Third-party code, not reviewed by us. Public PoCs are sometimes fake or contain malware. Read the code first and run it only in an isolated lab, against systems you are authorised to test.
