Description Eugene Teo (Security Response) 2010-11-09 05:57:03 UTC

Description of problem:
INET-DIAG is inconsistent about how it looks up the bytecode contained in a
netlink message, making it possible for a user to cause the kernel to execute
unaudited INET-DIAG bytecode. This can be abused to make the kernel enter an infinite loop, and possibly other consequences.

Red Hat would like to thank Nelson Elhage for reporting this issue.

Comment 3 Eugene Teo (Security Response) 2010-11-22 06:06:33 UTC

Statement:

This issue did not affect the version of Linux kernel as shipped with Red Hat Enterprise Linux 4 as it did not include support for monitoring of INET transport protocol sockets. Future updates in Red Hat Enterprise Linux 5, 6 and Red Hat Enterprise MRG may address this flaw.
