The remote host is missing updates announced in
advisory RHSA-2010:0147.
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
Security fixes:
* a NULL pointer dereference flaw was found in the sctp_rcv_ootb() function
in the Linux kernel Stream Control Transmission Protocol (SCTP)
implementation. A remote attacker could send a specially-crafted SCTP
packet to a target system, resulting in a denial of service.
(CVE-2010-0008, Important)
* a missing boundary check was found in the do_move_pages() function in
the memory migration functionality in the Linux kernel. A local user could
use this flaw to cause a local denial of service or an information leak.
(CVE-2010-0415, Important)
* a NULL pointer dereference flaw was found in the ip6_dst_lookup_tail()
function in the Linux kernel. An attacker on the local network could
trigger this flaw by sending IPv6 traffic to a target system, leading to a
system crash (kernel OOPS) if dst->neighbour is NULL on the target system
when receiving an IPv6 packet. (CVE-2010-0437, Important)
* a NULL pointer dereference flaw was found in the ext4 file system code in
the Linux kernel. A local attacker could use this flaw to trigger a local
denial of service by mounting a specially-crafted, journal-less ext4 file
system, if that file system forced an EROFS error. (CVE-2009-4308,
Moderate)
* an information leak was found in the print_fatal_signal() implementation
in the Linux kernel. When /proc/sys/kernel/print-fatal-signals is set to
1 (the default value is 0), memory that is reachable by the kernel could be
leaked to user-space. This issue could also result in a system crash. Note
that this flaw only affected the i386 architecture. (CVE-2010-0003,
Moderate)
* missing capability checks were found in the ebtables implementation, used
for creating an Ethernet bridge firewall. This could allow a local,
unprivileged user to bypass intended capability restrictions and modify
ebtables rules. (CVE-2010-0007, Low)
Users should upgrade to these updated packages, which contain backported
patches to correct these issues. The system must be rebooted for this
update to take effect.
Solution:
Please note that this update is available via
