Technical Description

Multiple vulnerabilities have been identified in Apple iPhone and iPod touch, which could be exploited by remote attackers to bypass security restrictions, disclose sensitive information, or take complete control of an affected device.

The first issue is caused by a memory corruption error in Safari when handling malformed URLs, which could be exploited by attackers to crash an affected browser or execute arbitrary code by enticing a user to access a maliciously crafted URL.

The second vulnerability is caused by an implementation error in the the Passcode Lock feature when handling emergency calls, which could allow malicious users with physical access to a vulnerable iPhone to launch an application without the passcode.

The third issue is caused by an input validation error in WebKit, which could be exploited to conduct cross site scripting attacks and gain knowledge of sensitive information.
