====================================================================== 4) Description of Vulnerability

Secunia Research has discovered multiple vulnerabilities in Autonomy Keyview, which can be exploited by malicious people to compromise a user's system.

1) A boundary error in the EML reader (emlsr.dll) when parsing certain headers ("To:", "Cc:", "Bcc:", "From:", "Date:", "Subject:", "Priority:", "Importance:", and "X-MSMail-Priority:") in EML files can be exploited to cause a heap-based buffer overflow via an overly long string.

2) A boundary error in the EML reader (emlsr.dll) when encountering the beginning of RFC2047 encoded-words in headers can be exploited to cause a heap-based buffer overflow via an overly long string.

3) A boundary error in the EML reader (emlsr.dll) when parsing the text string in RFC2047 encoded-words in headers can be exploited to cause a heap-based buffer overflow via an overly long string.

4) A boundary error in the EML reader (emlsr.dll) when creating a filename based on the subject in an EML file can be exploited to cause a heap-based buffer overflow via an overly long string.

====================================================================== 5) Solution

Update to version 10.4.0.0 or later.
