A vulnerability was found in KAME ipcomp (affected version unknown). It has been classified as critical. Affected is the function m_pulldown. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on availability. CVE summarizes:

The ipcomp6_input function in sys/netinet6/ipcomp_input.c in the KAME project before 20071201 does not properly check the return value of the m_pulldown function, which allows remote attackers to cause a denial of service (system crash) via an IPv6 packet with an IPComp header.

The bug was discovered 02/06/2008. The weakness was disclosed 02/07/2008 by mu-b as confirmed advisory (CERT.org). The advisory is available at kb.cert.org. This vulnerability is traded as CVE-2008-0177 since 01/09/2008. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details and a public exploit are known.

A public exploit has been developed by mu-b in ANSI C and been published 3 weeks after the advisory. The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 32477 (Mac OS X 10.5.x < 10.5.3 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family MacOS X Local Security Checks and running in the context l.

Upgrading eliminates this vulnerability. A possible mitigation has been published 4 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (40299), Tenable (32477) and Exploit-DB (5191). The entries 40317, 40044, 42635 and 42601 are pretty similar.
