CVE-2009-1238

TITLE

Apple Mac OS X of XNU include HFS vfs sysctl Interface race vulnerabilities

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. The Apple Mac OS X kernel is prone to multiple information-disclosure vulnerabilities. Successful exploits will allow attackers to obtain sensitive information that may aid in further attacks or to cause denial-of-service conditions. The problem arises because of the lack of exclusive locks on global variables. ---------------------------------------------------------------------- Secunia is pleased to announce the release of the annual Secunia report for 2008.

SOLUTION: Grant only trusted users access and restrict network access to affected systems.
