Detail
Problem Description: An update for libndp is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64 3. Description: Libndp is a library (used by NetworkManager) that provides a wrapper for the IPv6 Neighbor Discovery Protocol. It also provides a tool named ndptool for sending and receiving NDP messages. Security Fix(es): * It was found that libndp did not properly validate and check the origin of Neighbor Discovery Protocol (NDP) messages. An attacker on a non-local network could use this flaw to advertise a node as a router, allowing them to perform man-in-the-middle attacks on a connecting client, or disrupt the network connectivity of that client. (CVE-2016-3698) Red Hat would like to thank Julien Bernard (Viagénie) for reporting this issue. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 After installing this update, all running applications using libndp (for example, Network Manager) must be restarted for this update to take effect. 5. Bugs fixed (https://bugzilla.redhat.com/): 1329366 - CVE-2016-3698 libndp: denial of service due to insufficient validation of source of NDP messages |
