Description
Microsoft Internet Explorer 6.0 SP1 and possibly other versions allows remote attackers to cause a denial of service and possibly execute arbitrary code by instantiating COM objects as ActiveX controls, including (1) imskdic.dll (Microsoft IME), (2) chtskdic.dll (Microsoft IME), and (3) msoe.dll (Outlook), which leads to memory corruption. NOTE: it is not certain whether the issue is in Internet Explorer or the individual DLL files.
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.
