CVE-2010-0437 Detail

Description

The ip6_dst_lookup_tail function in net/ipv6/ip6_output.c in the Linux kernel before 2.6.27 does not properly handle certain circumstances involving an IPv6 TUN network interface and a large number of neighbors, which allows attackers to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via unknown vectors.

Vendor Statements (disclaimer)

Official Statement from Red Hat (03/25/2010)

Red Hat is aware of this issue and is tracking it via the following bug: https://bugzilla.redhat.com/CVE-2010-0437. This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 3 and 4, as they do not include support for Optimistic Duplicate Address Detection (DAD) in IPv6. This was addressed in Red Hat Enterprise Linux 5 via https://rhn.redhat.com/errata/RHSA-2010-9419.html. A future update in Red Hat Enterprise MRG may address this flaw.
