Linux developers fix a homemade network problem
Linux kernels 3.0.17, 3.1.9 and 3.2.1 fix a problem with the handling of IGMP packets that was introduced with updates in Linux 2.6.36. An IGMPv3 protocol packet being processed soon after the processing of an IGMPv2 packet could lead to a system crash caused by a kernel panic.
On 6 January, Simon McVittie reported strange crashes of his Linux notebook in the Debian bug database. Debian developer Ben Hutchings found that the problem was caused by a division by 0 that can occur with IGMP packets that have a Maximum Response Time of 0. As a result, Linux systems running a kernel version from 2.6.36 or later, up until the patched versions, can quite easily be crashed remotely using certain IGMP packets if a program has registered to receive multicast packets from the network. Typical examples for such programs include the avahi mDNS server or media players, such as VLC, that support RTP.Read More...
