Detailsinfo

A vulnerability has been found in Linux Kernel (Operating System) and classified as critical. Affected by this vulnerability is the function ip_append_data. The manipulation with an unknown input leads to a memory leak vulnerability. The CWE definition for the vulnerability is CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. As an impact it is known to affect availability. The summary by CVE is:

Memory leak in the icmp_push_reply function in Linux 2.6 before 2.6.12.6 and 2.6.13 allows remote attackers to cause a denial of service (memory consumption) via a large number of crafted packets that cause the ip_append_data function to fail, aka "DST leak in icmp_push_reply."

The bug was discovered 08/18/2005. The weakness was released 11/26/2005 (Website). The advisory is shared at marc.theaimsgroup.com. This vulnerability is known as CVE-2005-3848 since 11/26/2005. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are known, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 709 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 21977 (CentOS 4 : kernel (CESA-2006:0101)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 117771 (CentOS Security Update for Kernel (CESA-2006:0140)).

Upgrading to version 2.6 eliminates this vulnerability. A possible mitigation has been published 2 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (24499), Tenable (21977), SecurityFocus (BID 16044†), OSVDB (22506†) and Secunia (SA18203†).
