Vulnerability from variot
The kernel in Apple Mac OS X before 10.7.2 does not properly implement the sticky bit for directories, which might allow local users to bypass intended permissions and delete files via an unlink system call. Apple Mac OS X is prone to multiple security vulnerabilities that have been addressed in Security Update 2011-006. The update addresses new vulnerabilities that affect Application Firewall, ATS, CFNetwork, CoreMedia, CoreProcesses, CoreStorage, File Systems, IOGraphics, Kernel, MediaKit, Open Directory, QuickTime, SMB File Server, User Documentation, and libsecurity. These issues affect OS X prior to 10.7.2. Successful exploits will allow an attacker to delete files in a shared directory, which may aid in further attacks. Apple has released updates to address these vulnerabilities.
I. Apple has released updates to address these vulnerabilities.
II. Impact
A remote, unauthenticated attacker could execute arbitrary code, cause a denial of service, or gain unauthorized access to your files or system.
III. This advisory describes any known issues related to the updates and the specific impacts for each vulnerability. Administrators are encouraged to note these issues and impacts and test for any potentially adverse effects before wide-scale deployment.

Apple has\n released updates to address these vulnerabilities. \n\n\nI. Apple has released updates to address these\n vulnerabilities. \n\n\nII. Impact\n\n A remote, unauthenticated attacker could execute arbitrary code,\n cause a denial of service, or gain unauthorized access to your\n files or system. \n\n\nIII.
