Apple iPhone and iPod touch are prone to multiple remote vulnerabilities:
1. A vulnerability that may allow users to spoof websites.
2. An information-disclosure vulnerability.
3. A buffer-overflow vulnerability.
4. Two memory-corruption vulnerabilities.
Successfully exploiting these issues may allow attackers to execute arbitrary code, crash the affected application, obtain sensitive information, or direct unsuspecting victims to a spoofed site; other attacks are also possible.
These issues affect iPhone 1.0 through 1.1.4 and iPod touch 1.1 through 1.1.4.
