Description Eugene Teo (Security Response) 2012-01-10 07:58:32 UTC 
Commit 5b7c84066733c5dfb0e4016d939757b38de189e4 ('ipv4: correct IGMP behavior on v3 query during v2-compatibility mode') added yet another case for query parsing, which can result in max_delay = 0.  Substitute a value of 1, as in the usual v3 case.

Statement:

This issue did not affect the Linux kernel as shipped with Red Hat Enterprise Linux 4 as it did not backport the upstream commit 5b7c8406.
