Three of the vulnerabilities could allow someone to run code remotely, if an iPhone or iPod Touch user opened malicious audio or image files, or accessed a malicious FTP (File Transfer Protocol) server, Apple said.
Another vulnerability could allow someone with physical access to one of the devices to bypass the passcode on a locked device and access the data.
The patch affects iPhone OS 3.1.3 and iPhone OS 3.1.3 for iPod Touch. More information is on the Apple security Web page.
