Following the exploit fix in PHPFusion 6.01.3, it has come to my attention that files planted prior to 6.01.3 are lying dormant on servers. The patched code only protects against newly uploaded images. To combat this I have produced two infusions, a Forum Attachment Image Checker and an Avatar Image Checker. These infusions enable administrators to safely inspect Forum Attachment Images and Avatar Images. Any malformed images will appear as broken images, if you find any, delete them. You are strongly advised to use these tools at least once.
