Discussion

Apple Mac OS X CoreFoundation (CVE-2011-0201) Buffer Overflow Vulnerability

Apple Mac OS X is prone to an off-by-one buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data.

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.

This issue affects Mac OS X 10.6 through 10.6.7 and Mac OS X Server 10.6 through 10.6.7.

NOTE: This issue was previously discussed in BID 48412 (Apple Mac OS X Prior to 10.6.8 Multiple Security Vulnerabilities) but has been given its own record to better document it.
