TITLE

Apple iOS of WebKit Vulnerable to arbitrary code execution

DESCRIPTION

WebKit, as used in Apple iOS before 4.3, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site, a different vulnerability than other CVEs listed in APPLE-SA-2011-03-09-1. WebKit is prone to an unspecified memory-corruption vulnerability. An attacker can exploit this issue by enticing an unsuspecting user into visiting a malicious webpage with a vulnerable application. Very few technical details are currently available. We will update this BID when more information emerges. Successful exploits will allow attackers to execute arbitrary code in the context of the affected browser or cause denial-of-service conditions; other attacks may also be possible. Apple iOS is an operating system developed by Apple (Apple) for mobile devices. ---------------------------------------------------------------------- Get a tax break on purchases of Secunia Solutions!
