Secunia Research has discovered a vulnerability in WinHKI versions 1.66 and 1.67, which can be exploited by malicious people to compromise a user’s system. The vulnerability is caused due to a boundary error in ztvunacev2.dll (UNACEV2.DLL) when extracting an ACE archive containing a file with an overly long filename. This can be exploited to cause a stack-based buffer overflow when a user extracts a specially crafted ACE archive.
