CVE-2009-2836


TITLE

Apple Mac OS X Login window vulnerabilities to log in with arbitrary accounts

Trust: 0.8

sources: JVNDB: JVNDB-2009-002339

DESCRIPTION

Race condition in Login Window in Apple Mac OS X 10.6.x before 10.6.2, when at least one account has a blank password, allows attackers to bypass password authentication and obtain login access to an arbitrary account via unspecified vectors. Apple Mac OS X is prone to a race-condition vulnerability in Login Window. Under certain circumstances, a local attacker can exploit this issue to access the system with elevated privileges. This issue affects the following: Mac OS X 10.6 and 10.6.1 Mac OS X Server 10.6 and 10.6.1 NOTE: This issue was previously covered in BID 36956 (Apple Mac OS X 2009-006 Multiple Security Vulnerabilities), but has been assigned its own record to better document it
