Title: Apple Mac OS X CoreText Unicode String Handling Heap Based Buffer Overflow Vulnerability
Severity: HIGH
Description:
Apple Mac OS X is prone to a heap-based buffer-overflow vulnerability that affects the CoreText component.
An attacker can exploit this issue by enticing an unsuspecting user to handle maliciously crafted Unicode strings, such as when viewing a maliciously crafted webpage.
The attacker can exploit this issue to execute arbitrary code in the context of the application using the component. Failed exploit attempts will result in a denial-of-service condition.
