Permissions, Privileges, and Access Controls
The default configuration of Safari in Apple Mac OS X 10.4 through 10.4.10 adds a private key to the keychain with permissions that allow other applications to access the key without warning the user, which might allow other applications to bypass intended access restrictions.
CWE-264 - Permissions Privileges and Access Controls
CWE 264 (permissions, privileges, and access controls) is not a weakness in and of itself, rather it is a category of weaknesses related to the management of permissions, privileges, and other security features used to perform access control. If not addressed, the weaknesses in this category allow attackers to gain privileges for an unintended sphere of control, access sensitive information, and execute arbitrary commands.
