FileVault in Mac OS X 10.4.5 and earlier does not properly mount user directories when creating a FileVault image, which allows local users to access protected files when FileVault is enabled.
This is a vulnerability exploitable with only local access requires the attacker to have either
physical access to the vulnerable system or a local (shell) account. Examples of locally
exploitable vulnerabilities are peripheral attacks such as Firewire/USB DMA attacks, and
local privilege escalations (e.g., sudo).
Specialized access conditions or extenuating circumstances do not exist. The following are examples:
The affected product typically requires access to a wide range of systems and users, possibly anonymous an untrusted (e.g., Internet-facing web or mail server).
The affected configuration is default or ubiquitous. The attack can be performed manually and requires little skill or additional information gathering.
The 'race condition' is a lazy one (i.e., it is technically a race but easily winnable).
One instance of authentication is required to access and exploit the vulnerability.
There is considerable informational disclosure. Access to some system files is
possible, but the attacker does not have control over what is obtained, or the scope of
the loss is constrained. An example is a vulnerability that divulges only certain tables
in a database.
There is no impact to the integrity of the system.
There is no impact to the availability of the system.
