Description

The version of the IrfanView DjVu plugin (DjVu.dll) was found to be less than 4.34. As such, it is reportedly affected by a heap-based buffer overflow vulnerability that can be triggered by tricking users into opening a .djvu file with a specially crafted DjVu image that is not properly handled during decompression. Successful exploitation may allow arbitrary code to be executed on the affected host.
