Detailsinfo

A vulnerability has been found in Linux Kernel 2.6.16.59 (Operating System) and classified as critical. Affected by this vulnerability is the function icmp_send. The manipulation with an unknown input leads to a denial of service vulnerability. The CWE definition for the vulnerability is CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. As an impact it is known to affect availability. The summary by CVE is:

The icmp_send function in net/ipv4/icmp.c in the Linux kernel before 2.6.25, when configured as a router with a REJECT route, does not properly manage the Protocol Independent Destination Cache (aka DST) in some situations involving transmission of an ICMP Host Unreachable message, which allows remote attackers to cause a denial of service (connectivity outage) by sending a large series of packets to many destination IP addresses within this REJECT route, related to an "rt_cache leak."

The bug was discovered 03/11/2009. The weakness was released 03/12/2009 as Bug 485163 as confirmed bug report (Bugzilla). The advisory is shared at bugzilla.redhat.com. This vulnerability is known as CVE-2009-0778 since 03/03/2009. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are known, but no exploit is available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1088 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 43729 (CentOS 5 : kernel (CESA-2009:0326)), 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 155920 (Oracle Enterprise Linux Update for Kernel (ELSA-2009-0326)).

Upgrading eliminates this vulnerability. A possible mitigation has been published 3 weeks after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (49199), Tenable (43729), SecurityFocus (BID 34084†), OSVDB (56444†) and Secunia (SA33758†).
