Discussion

Apple Mac OS X SFNT Tables Multiple Buffer Overflow Vulnerabilities

Apple Mac OS X is prone to multiple buffer-overflow vulnerabilities because it fails to properly bounds check user-supplied input.

Successful exploits may allow an attacker to execute arbitrary code in the context of the 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.
