The team behind LuckyCal, an events-focused startup, has discovered a unique bug that impacts iPhone applications that use Facebook Connect. The UID overflow bug could affect about 10 percent, or 25 million, Facebook users. The fix is pretty simple, according to LuckyCal founder Sanjay Vakil. The company has shared a way to patch it on its blog.
“The overflow appears to have occurred a few months back, and Facebook’s amazing growth has resulted in anyone who signed up after June being touched by the bug,” according to LuckyCal’s blog. “The impact is that no Facebook Connect-ed iPhone applications will work for those users.” Of course, this assumes that app developers haven’t independently patched the code. To be clear, I have not been impacted myself yet. Have you been affected? Do let us know.
Update: Facebook spokeswoman emailed us to let us know that “the bug in the Facebook Connect for iPhone SDK has been fixed. Developers can download an updated, more scalable code from here. iPhone applications integrated with Facebook Connect will continue to function as normal.”
