>> Apple iPod touch Code Execution and Security Bypass Vulnerabilities
|
Multiple vulnerabilities have been identified in Apple iPod touch, which could be exploited by attackers to bypass security restrictions, poison DNS cache, cause a denial of service or compromise a vulnerable system.
The first issue is caused by an error in the Application Sandbox that does not properly enforce access restrictions between third-party applications, which may allow a third-party application to read files in another third-party application's sandbox and lead to the disclosure of sensitive information.
The second vulnerability is caused by an error in mDNSResponder, which may allow DNS cache poisoning attacks.
The third weakness is caused due to predictable TCP initial sequence numbers being generated, which could allow a remote attacker to create a spoofed TCP connection or insert data into an existing TCP connection.
The fourth vulnerability is caused by a use-after-free error in WebKit when handling CSS import statements, which could allow malicious websites to crash an affected application or execute arbitrary code.
Other vulnerabilities caused by errors in FreeType could be exploited to execute arbitrary code. For additional information, see : VUPEN/ADV-2008-1794
