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. SOLUTION: Update to version 10.4.0.0 or later. PROVIDED AND/OR DISCOVERED BY: 1-4) Secunia Research 5-9) Dyon Balding, Secunia Research. 10-13) Carsten Eiram, Secunia Research.
