Description


Secunia Research has discovered two vulnerabilities in IrfanView, which can be exploited by malicious people to compromise a user's system.

1) A sign-extension error when parsing certain PSD images can be exploited to cause a heap-based buffer overflow by tricking a user into opening a specially crafted PSD file.

2) A boundary error when processing certain RLE compressed PSD images can be exploited to cause a heap-based buffer overflow by tricking a user into opening a specially crafted PSD file.

Successful exploitation of the vulnerabilities may allow execution of arbitrary code.

The vulnerabilities are confirmed in version 4.25. Other versions may also be affected.


Solution:
Update to version 4.27.

Provided and/or discovered by:
Stefan Cornelius, Secunia Research.
