Foxit Reader "util.printf()" Buffer Overflow
------------------------------------------------------------------------


SUMMARY

" <http://www.foxitsoftware.com/pdf/rd_intro.php> Foxit Reader is a free
PDF document viewer and printer, with incredible small size (only 2.55 M
download size), breezing-fast launch speed and rich feature set. Foxit
Reader supports Windows Me/2000/XP/2003/Vista. Its core function is
compatible with PDF Standard 1.7." Secunia Research has discovered a
vulnerability in Foxit Reader, which can be exploited by malicious people
to compromise a user's system.

DETAILS

Vulnerable Systems:

overflow via a specially crafted PDF file.
