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 220.127.116.11 of the Formats plug-in using IrfanView version 4.00. Other versions may also be affected.
