TITLE

WebKit Vulnerable to arbitrary code execution

DESCRIPTION

Use-after-free vulnerability in WebKit, as used in Apple Safari before 5.0.5; iOS before 4.3.2 for iPhone, iPod, and iPad; iOS before 4.2.7 for iPhone 4 (CDMA); and possibly other products allows remote attackers to execute arbitrary code by adding children to a WBR tag and then removing the tag, related to text nodes, as demonstrated by Chaouki Bekrar during a Pwn2Own competition at CanSecWest 2011. WebKit Contains a flaw in the execution of arbitrary code due to a flaw in processing related to text nodes.A third party may execute arbitrary code. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the way the Webkit library handles WBR tags on a webpage. By adding children to a WBR tag and then consequently removing the tag through, for example, a 'removeChild' call it is possible to create a dangling pointer that can result in remote code execution under the context of the current user. Attackers can exploit this issue by enticing an unsuspecting user into visiting a malicious webpage. Failed exploit attempts will result in a denial-of-service condition.
