The remote host is missing updates announced in
advisory RHSA-2007:0347.
The Linux kernel handles the basic functions of the operating system.
These new kernel packages contain fixes for the following security issues:
* a flaw in the handling of IPv6 type 0 routing headers that allowed remote
users to cause a denial of service that led to a network amplification
between two routers (CVE-2007-2242, Important).
* a flaw in the nfnetlink_log netfilter module that allowed a local user to
cause a denial of service (CVE-2007-1496, Important).
* a flaw in the flow list of listening IPv6 sockets that allowed a local
user to cause a denial of service (CVE-2007-1592, Important).
* a flaw in the handling of netlink messages that allowed a local user to
cause a denial of service (infinite recursion) (CVE-2007-1861, Important).
* a flaw in the IPv4 forwarding base that allowed a local user to cause an
out-of-bounds access (CVE-2007-2172, Important).
* a flaw in the nf_conntrack netfilter module for IPv6 that allowed remote
users to bypass certain netfilter rules using IPv6 fragments
(CVE-2007-1497, Moderate).
In addition to the security issues described above, fixes for the following
have been included:
* a regression in ipv6 routing.
* an error in memory initialization that caused gdb to output inaccurate
backtraces on ia64.
* the nmi watchdog timeout was updated from 5 to 30 seconds.
* a flaw in distributed lock management that could result in errors during
virtual machine migration.
* an omitted include in kernel-headers that led to compile failures for
some packages.
Red Hat Enterprise Linux 5 users are advised to upgrade to these packages,
which contain backported patches to correct these issues.
