Secunia Research has discovered a vulnerability in Autonomy KeyView, which can be exploited by malicious people to compromise a vulnerable system. The vulnerability is caused by a boundary error in the Spreadsheet Lotus 123 reader (wkssr.dll) when converting floating point values in certain record types. This can be exploited to cause a stack-based buffer overflow via a specially crafted file. Successful exploitation allows execution of arbitrary code. Autonomy KeyView versions 10.4 and 10.9 are affected.
