Description:
Some vulnerabilities have been reported in the Linux Kernel, which potentially can be exploited by malicious people to bypass certain security restrictions or cause a DoS (Denial of Service).
1) NULL pointer dereferences within net/netfilter/nfnetlink_log.c can potentially be exploited to cause a kernel panic by sending specially crafted packets to a vulnerable system.
2) An error exists within conntrack when assembling fragmented IPv6 packets. This can potentially be exploited to bypass certain rulesets that accept ESTABLISHED packets early.
