DESCRIPTION:
Secunia Research has discovered some vulnerabilities in libgdiplus
for Mono, which can be exploited by malicious people to compromise an
application using the library.

1) An integer overflow error within the "gdip_load_tiff_image()"
function in src/tiffcodec.c can be exploited to cause a heap-based
buffer overflow by e.g. processing specially crafted TIFF images in
an application using the library.

2) An integer overflow error within the
"gdip_load_jpeg_image_internal()" function in src/jpegcodec.c can be
exploited to cause a heap-based buffer overflow by e.g. processing
specially crafted JPEG images in an application using the library.

3) An integer overflow error within the "gdip_read_bmp_image()"
function in src/bmpcodec.c can be exploited to cause a heap-based
buffer overflow by e.g. processing specially crafted BMP images in an
application using the library.

The vulnerabilities are confirmed in version 2.6.7. Other versions
may also be affected.

SOLUTION:
Do not process untrusted images in an application using the library.

PROVIDED AND/OR DISCOVERED BY:
Stefan Cornelius, Secunia Research.
