Description:
Tielei Wang has discovered a vulnerability in IrfanView, which can be exploited by malicious people to potentially compromise a user's system.
The vulnerability is caused due to an integer overflow when resampling certain 1 BPP images. This can be exploited to cause a heap-based buffer overflow by e.g. tricking a user into opening a specially crafted TIFF file.
Successful exploitation requires that a resampling or screen fitting option is used.
The vulnerability is confirmed in version 4.23. Other versions may also be affected.
