TITLE

Apple Mac OS X of CoreProcesses Vulnerabilities that prevent access restrictions on components

DESCRIPTION

The CoreProcesses component in Apple Mac OS X 10.7 before 10.7.2 does not prevent a system window from receiving keystrokes in the locked-screen state, which might allow physically proximate attackers to bypass intended access restrictions by typing into this window. 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. Apple Mac OS X is prone to a local security-bypass vulnerability. Successful exploits may lead to other attacks. NOTE: This issue was previously discussed in BID 50085 (Apple Mac OS X Prior to 10.7.2 Multiple Security Vulnerabilities) but has been given its own record to better document it. 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. IV.
