Detailsinfo

A vulnerability was found in Linux Kernel 2.1.132 (Operating System). It has been rated as problematic. This issue affects an unknown code of the file /dev/urandom. The manipulation with an unknown input leads to a resource consumption vulnerability. Using CWE to declare the problem leads to CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. Impacted is availability. The summary by CVE is:

Linux 2.1.132 and earlier allows local users to cause a denial of service (resource exhaustion) by reading a large buffer from a random device (e.g. /dev/urandom), which cannot be interrupted until the read has completed.

The weakness was released 12/27/1998 as not defined posting (Bugtraq). It is possible to read the advisory at marc.theaimsgroup.com. The identification of this vulnerability is CVE-1999-1285. The exploitation is known to be easy. Attacking locally is a requirement. No form of authentication is needed for a successful exploitation. Technical details of the vulnerability are known, but there is no available exploit.

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (1472) and OSVDB (13024†). Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
