Tielei Wang has discovered a vulnerability in Google Picasa, which can be exploited by malicious people to potentially compromise a user's system.

The vulnerability is caused due to an integer overflow error in PicasaPhotoViewer.exe when processing JPEG files. This can be exploited to cause a heap-based buffer overflow by tricking a user into opening a specially crafted JPEG file and e.g. zooming in.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is confirmed in PicasaPhotoViewer.exe version 3.6.95.25, included in Google Picasa 3.6 build 95.25. Prior versions may also be affected.

Solution
Update to version 3.6 build 105.41.
