Description Tomas Hoger 2008-02-01 11:13:37 EST
Secunia has published an advisory regarding flaws in gnumerinc's XLS parser:

  http://secunia.com/advisories/28725/

Quoting the advisory:
  The vulnerability is caused due to integer overflows and signedness errors
  when processing XLS HLINK opcodes within the "excel_read_HLINK()" function
  in plugins/excel/ms-excel-read.c. This can be exploited to corrupt the stack
  via a specially crafted XLS file.

  Successful exploitation allows execution of arbitrary code.

  The vulnerability is confirmed in version 1.6.3. Versions prior to 1.8.1 may
  also be affected.

Described issue should be fixed in upstream version 1.8.1.
