Discussion

WebKit Malformed XHTML Tags Use After Free Memory Corruption Vulnerability

WebKit is prone to a memory corruption vulnerability.

Attackers can exploit this issue by enticing an unsuspecting user into visiting a malicious webpage.

Successful attacks may result in information disclosure, remote code execution, denial of service, or other consequences. Failed exploit attempts will result in a denial-of-service condition.

NOTE: This issue was previously discussed in 48808 (Apple Safari Prior to 5.1 and 5.0.6 Multiple Security Vulnerabilities) but has been given its own record to better document it.
