Parvez Anwar has discovered a vulnerability in IrfanView PlugIns, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to an error in the JPEG2000 plug-in when processing the Quantization Default (QCD) marker segment. This can be exploited to cause a stack-based buffer overflow via a specially crafted JPEG2000 (JP2) file.
Successful exploitation allows execution of arbitrary code, but requires tricking a user into opening a malicious file.
The vulnerability is confirmed in version 4.32. Other versions may also be affected.
Solution: Update the JPEG2000 plug-in to version 4.33.
Provided and/or discovered by: Parvez Anwar via Secunia.
