Detailsinfo

A vulnerability was found in Linux Kernel 2.4.0/2.6.0 (Operating System). It has been rated as problematic. Affected by this issue is the function do_fork. The manipulation with an unknown input leads to a memory leak vulnerability. Using CWE to declare the problem leads to CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. Impacted is availability. CVE summarizes:

The do_fork function in Linux 2.4.x before 2.4.26, and 2.6.x before 2.6.6, does not properly decrement the mm_count counter when an error occurs after the mm_struct for a child process has been activated, which triggers a memory leak that allows local users to cause a denial of service (memory exhaustion) via the clone (CLONE_VM) system call.

The bug was discovered 04/22/2004. The weakness was shared 07/07/2004 with Redhat (Website). The advisory is available at marc.theaimsgroup.com. This vulnerability is handled as CVE-2004-0427 since 04/29/2004. The exploitation is known to be easy. Local access is required to approach this attack. No form of authentication is required for exploitation. Technical details are known, but there is no available exploit.

The vulnerability was handled as a non-public zero-day exploit for at least 57 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 12509 (RHEL 2.1 : kernel (RHSA-2004:260)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Red Hat Local Security Checks and running in the context l.

Upgrading to version 2.4.26 or 2.6.6 eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (16002), Tenable (12509), SecurityFocus (BID 10221†), OSVDB (7219†) and Secunia (SA11429†). The entry VDB-21912 is related to this item. If you want to get best quality of vulnerability data, you may have to visit VulDB.
