Apple Mac OS X HFS Subsystem Information Disclosure Vulnerability
Apple Mac OS X is prone to a local information-disclosure vulnerability because of an integer-overflow error in the HFS subsystem.
A local attacker can exploit this issue to obtain sensitive information that may lead to further attacks. Due to the nature of this issue, local attackers may be able to execute arbitrary code in the context of the kernel, but this has not been confirmed.
Versions prior to OS X 10.6.7 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.
