A race condition in MandrakeUpdate allows local users to modify RPM files while they are in the /tmp directory before they are installed.
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 exist. For example,
in most configurations, the attacking party must already have elevated privileges or spoof additional systems
in addition to the attacking system (e.g., DNS hijacking).
The attack depends on social engineering methods that would be easily detected by knowledgeable people.
For example, the victim must perform several suspicious or atypical actions.
The vulnerable configuration is seen very rarely in practice.
If a race condition exists, the window is very narrow.
Authentication is not required to access and exploit the vulnerability.
There is no impact to the confidentiality of the system.
Modification of some system files or information is possible, but the attacker does not
have control over what can be modified, or the scope of what the attacker can affect is
limited. For example, system or application files may be overwritten or modified, but
either the attacker has no control over which files are affected or the attacker can
modify files within only a limited context or scope.
There is no impact to the availability of the system.
