Description Petr Matousek 2011-02-16 23:48:07 UTC 
Description of problem:
It was found that executing bridge snooping code triggered by host originated IGMP packets could cause corruption in 512-byte slabs, most commonly leading to crashes in jbd2. This could be possibly exploited by local unprivileged user to crash the host (DoS).

Comment 2 Petr Matousek 2011-02-16 23:51:30 UTC 
Statement:

This issue did not affect the versions of the Linux kernel as shipped with Red
Hat Enterprise Linux 4, 5, and Red Hat Enterprise MRG as they did not include
support for the bridge snooping functionality. A future update in Red Hat
Enterprise Linux 6 may address this flaw.
Comment 5 errata-xmlrpc 2011-04-08 02:57:47 UTC 
This issue has been addressed in following products:

  Red Hat Enterprise Linux 6
