Vulnerability Title
N/A
Vulnerability Description
Race condition in the HFS vfs sysctl interface in XNU 1228.8.20 and earlier on Apple Mac OS X 10.5.6 and earlier allows local users to cause a denial of service (kernel memory corruption) by simultaneously executing the same HFS_SET_PKG_EXTENSIONS code path in multiple threads, which is problematic because of lack of mutex locking for an unspecified global variable.

Apple Mac OS X 'HFS_SET_PKG_EXTENSIONS' 多个本地信息泄露漏洞
Vulnerability Description
Apple Mac OS X 10.5.6及之前版本的平台上的XNU 1228.8.20及之前版本中的HFS sysctl界面存在多个本地信息泄露漏洞。本地用户可以通过在多个threads中同时执行同一个HFS_SET_PKG_EXTENSIONS代码路径，来引起拒绝服务攻击(内存破坏)。该问题之所以产生，是因为对全局变量缺乏互斥锁定。
