>> Apple iPhone Multiple Remote Code Execution and Security Bypass Vulnerabilities
|
Multiple vulnerabilities have been identified in Apple iPhone, which could be exploited by malicious web sites to take complete control of an affected system or conduct spoofing, cross site and cross domain scripting attacks.
The first issue is caused by a race condition in page updating, which could be combined with HTTP redirection to allow JavaScript from one page to modify a redirected page and conduct cross-domain scripting attacks.
The second vulnerability is caused by a heap overflow error in the Perl Compatible Regular Expressions (PCRE) library used by the JavaScript engine, which could be exploited by remote attackers to execute arbitrary code by tricking a user into visiting a malicious web page.
The third issue is caused by an error in XMLHttpRequest when serializing headers into an HTTP request, which could be exploited to conduct cross-site scripting attacks by tricking a user into visiting a specially crafted web page.
The fourth vulnerability is caused by an error when processing domain names containing Unicode characters, which could be exploited to masquerade a website and conduct spoofing attacks.
The fifth issue is caused by an invalid type conversion in WebKit when rendering frame sets, which could be exploited by attackers to compromise an affected systeme by tricking a user into visiting a malicious web page.
