Impact by CVSS Score
  • ID: CVE-2006-0457
Summary:

Race condition in the (1) add_key, (2) request_key, and (3) keyctl functions in Linux kernel 2.6.x allows local users to cause a denial of service (crash) or read sensitive kernel memory by modifying the length of a string argument between the time that the kernel calculates the length and when it copies the data into kernel memory.

Exploitability Analysis:

This is a vulnerability exploitable with network access which means the vulnerable software is bound to the network stack and the attacker does not require local network access or local access to exploit it. Such a vulnerability is often termed “remotely exploitable”.

Exploitability Complexity:

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:

Authentication is not required to access and exploit the vulnerability.

Confidentiality Impact:

There is total information disclosure, resulting in all system files being revealed. The attacker is able to read all of the system's data (memory, files, etc.).

Integrity Impact:

There is no impact to the integrity of the system.

Availability Impact:

There is a total shutdown of the affected resource. The attacker can render the resource completely unavailable.
