DESCRIPTION:
Secunia Research has discovered two vulnerabilities in SumatraPDF,
which can be exploited by malicious people to compromise a user's
system.

1) An integer overflow error within the "loadsamplefunc()" function
in mupdf/pdf_function.c can be exploited to cause a heap-based buffer
overflow by e.g. tricking a user into opening a specially crafted PDF
file containing a sample function with a specially crafted size.

2) An integer overflow error within the "fz_newpixmap()" function in
mupdf/fitz/res_pixmap.c can be exploited to cause a heap-based buffer
overflow by e.g. tricking a user into opening a specially crafted PDF
file containing an image with specially crafted dimensions.

The vulnerabilities are confirmed in version 1.2. Other versions may
also be affected.

SOLUTION:
Update to version 1.3.
