Description

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

1) A boundary error within the HTML speed reader (htmsr.dll) when handling links in e.g. the "background" attribute of <BODY> tags can be exploited to cause a stack-based buffer overflow.

2) A boundary error within the HTML speed reader (htmsr.dll) when handling e.g. the "src" attribute of <IMG> tags can be exploited to cause a stack-based buffer overflow.

3) A boundary error within the HTML speed reader (htmsr.dll) when handling large chunks of data inside an HTML document can be exploited to cause a heap-based buffer overflow.

4) A boundary error within kvdocve.dll when processing overly long paths can be exploited to cause a buffer overflow via e.g. an overly long link inside the "src" attribute of an <IMG> tag within an HTML document.

5) 21 boundary errors within the "Folio Flat File" speed reader (foliosr.dll) when handling attribute values of a number of tags (eg. DI, FD, FT, JD, JL, LE, OB, OD, OL, PN, PS, PW, RD, QL, or TS) can be exploited to cause stack-based buffer overflows.

6) An unsafe call to "sscanf()" in the Applix Graphics reader (kpagrdr.dll) when parsing the "ENCODING" attribute of the "*BEGIN" tag can be exploited to cause a stack-based buffer overflow.

7) A boundary error in the Applix Graphics reader (kpagrdr.dll) when parsing overly long tokens from the input file can be exploited to cause a heap-based buffer overflow.

8) A boundary error in the Applix Graphics reader (kpagrdr.dll) when parsing the initial "*BEGIN" tag can be exploited to cause stack-based buffer overflow.

9) A logic error in the Applix Graphics reader (kpagrdr.dll) when parsing long tokens can result in an infinite loop. Exploitation will result in maximum CPU usage until an application-configured timeout expires. In some cases memory usage will increase until the OS terminates the process.

10) 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.

11) 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.

12) 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.

13) 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.
