http://secunia.com/advisories/25052/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
IrfanView Formats Plug-in 4.x
http://secunia.com/product/14080/

DESCRIPTION:
Marsu has discovered a vulnerability in IrfanView's Formats plug-in,
which can be exploited by malicious people to compromise a user's
system.

The vulnerability is caused due to a boundary error within the
Formats plug-in (Formats.dll) when handling IFF files. This can be
exploited to cause a stack-based buffer overflow via a specially
crafted IFF file.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in version 4.0.0.0 of the Formats
plug-in using IrfanView version 4.00. Other versions may also be
affected.

SOLUTION:
Do not open untrusted IFF files.
