An Apple spokeswoman said in a statement, "We're aware of this reported issue, we have already developed a fix and it will be available to customers in an upcoming software update." No release date was given for the update.
Previously, Apple had announced it was "investigating" the issue.
iPhone Dev Team hacker "comex" was the first to exploit the security flaws, allowing users to jailbreak their iOS devices. Early users of the browser-based jailbreak exploit reported problems with FaceTime and MMS services, but the issues were quickly addressed by the iPhone Dev Team.
The vulnerabilities have attracted significant attention this week. Several security firms have issued notices labeling the vulnerabilities "critical." A German government agency warned users Wednesday to avoid opening PDF files on their devices until a software fix is released.
This isn't the first time the German government has expressed concern over security on the iPhone 4 and iOS. In June, a German official asked for clarification on Apple's use of personal data collected from German iPhone 4 users, as reported by The New York Times. Sabine Leutheusser-Schnarrenberger, the justice minister for Germany, requested information from Apple outlining the kind of data collected and the reason for its collection.
