CVE-2007-0738

TITLE

Kerberos administration daemon may free uninitialized pointers

DESCRIPTION

The Login Window in Apple Mac OS X 10.4 through 10.4.9 does not display the screen saver authentication dialog in certain circumstances when waking from sleep, even though the "require a password to wake the computer from sleep" option is enabled, which allows local users to bypass authentication controls. A vulnerability exists in the Kerberos administration daemon that may allow a remote, unauthenticated user to free uninitialized pointers. Freeing uninitialized pointers corrupts memory in a way that could allow an attacker to execute code. As a result, there is a problem that the authentication dialog is avoided.Since the authentication dialog box does not appear when waking from sleep, a user who has physical access to the system may be logged in without authentication. Apple Mac OS X is prone to multiple security vulnerabilities. These issues affect Mac OS X and various applications, including AFP Client, AirPortDriver module, CoreServices, Libinfo, Login Window, Natd, SMB, System Configuration, URLMount, VideoConference framework, WebDAV, and WebFoundation. Attackers may exploit these issues to execute arbitrary code, trigger denial-of-service conditions, escalate privileges, overwrite files, and access potentially sensitive information. Both local and remote vulnerabilities are present. Apple Mac OS X 10.4.9 and prior versions are vulnerable to these issues. In some cases the user's \"Wake computer from hibernation requires password\" number was ignored, resulting in no password being asked after waking from hibernation. ---------------------------------------------------------------------- Secunia is proud to announce the availability of the Secunia Software Inspector.
