Multiple vulnerabilities in Apple iOS could allow an unauthenticated, remote attacker to access sensitive information, cause a denial of service (DoS) condition, or execute arbitrary code.
Apple iOS 7 addresses the vulnerabilities, which are due to multiple errors in processing attacker-supplied input in iOS as well as in third-party libraries and components, including WebKit. An unauthenticated, remote attacker could exploit the vulnerabilities by convincing a user to view a malicious website on a vulnerable device. If successful, the attacker could access sensitive information, execute arbitrary code, or cause a DoS condition on the device.
This update also addresses multiple vulnerabilities in Safari that could allow an unauthenticated, remote attacker to gain access to sensitive information or execute arbitrary code. Lastly, the update addresses multiple vulnerabilities in the kernel of affected iOS devices that could allow an attacker to execute arbitrary code, cause a DoS, or gain access to sensitive information.
Apple confirmed the vulnerabilities in a security advisory and released software updates.
