Hi All.
I have added patches to the 3 kernel module in the moonbase which fixes
a kernel security bug.
Here is a description provided in the patch.
# Several hash table implementations in the networking were
# remotely exploitable. Remote attackers could launch attacks
# whereby, using carefully choosen forged source addresses, make
# every routing cache entry get hashed into the same hash chain.
#
# Netfilter's IP conntrack module and the TCP syn-queue implementation
# had identical vulnerabilities and have been fixed too.
#
# The choosen solution to the problem involved using Bob's Jenkins
# hash along with a randomly choosen input. For the ipv4 routing
# cache we take things one step further and periodically choose a
# new random secret. By default this happens every 10 minutes, but
# this is configurable by the user via sysctl knobs.
Here is the RedHat advisory:
