Discussion

Apple Mac OS X CoreText Memory Corruption Vulnerability

Apple Mac OS X is prone to a memory-corruption vulnerability.

An attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition.

Mac OS X versions 10.6 through 10.6.6 and Mac OS X Server versions 10.6 through 10.6.6 are vulnerable.

NOTE: This issue was previously discussed in BID 46950 (Apple Mac OS X Prior to 10.6.7 Multiple Security Vulnerabilities) but has been given its own record to better document it.
