Description
It was discovered that NetworkManager would set device MTUs based on MTU
values received in IPv6 RAs (Router Advertisements), without sanity
checking the MTU value first. A remote attacker could exploit this flaw to
create a denial of service attack, by sending a specially crafted IPv6 RA
packet to disturb IPv6 communication. (CVE-2015-0272)
A flaw was found in the way NetworkManager handled router advertisements.
An unprivileged user on a local network could use IPv6 Neighbor Discovery
ICMP to broadcast a non-route with a low hop limit, causing machines to
lower the hop limit on existing IPv6 routes. If this limit is small enough,
IPv6 packets would be dropped before reaching the final destination.
(CVE-2015-2924)
The network-manager-applet and NetworkManager-libreswan packages have been
upgraded to upstream versions 1.0.6, and provide a number of bug fixes and
enhancements over the previous versions. (BZ#1177582, BZ#1243057)
