The remote Scientific Linux host is missing one or more security
This update fixes the following security issues :
- A flaw was found in the sctp_icmp_proto_unreachable()
function in the Linux kernel's Stream Control
Transmission Protocol (SCTP) implementation. A remote
attacker could use this flaw to cause a denial of
service. (CVE-2010-4526, Important)
- A missing boundary check was found in the dvb_ca_ioctl()
function in the Linux kernel's av7110 module. On systems
that use old DVB cards that require the av7110 module, a
local, unprivileged user could use this flaw to cause a
denial of service or escalate their privileges.
- A race condition was found in the way the Linux kernel's
InfiniBand implementation set up new connections. This
could allow a remote user to cause a denial of service.
- A heap overflow flaw in the iowarrior_write() function
could allow a user with access to an IO-Warrior USB
device, that supports more than 8 bytes per report, to
cause a denial of service or escalate their privileges.
- A flaw was found in the way the Linux Ethernet bridge
implementation handled certain IGMP (Internet Group
Management Protocol) packets. A local, unprivileged user
on a system that has a network interface in an Ethernet
bridge could use this flaw to crash that system
- A NULL pointer dereference flaw was found in the Generic
Receive Offload (GRO) functionality in the Linux
kernel's networking implementation. If both GRO and
promiscuous mode were enabled on an interface in a
virtual LAN (VLAN), it could result in a denial of
service when a malformed VLAN frame is received on that
interface. (CVE-2011-1478, Moderate)
- A missing initialization flaw in the Linux kernel could
lead to an information leak. (CVE-2010-3296, Low)
- A missing security check in the Linux kernel's
implementation of the install_special_mapping() function
could allow a local, unprivileged user to bypass the
mmap_min_addr protection mechanism. (CVE-2010-4346, Low)
- A logic error in the orinoco_ioctl_set_auth() function
in the Linux kernel's ORiNOCO wireless extensions
support implementation could render TKIP countermeasures
ineffective when it is enabled, as it enabled the card
instead of shutting it down. (CVE-2010-4648, Low)
- A missing initialization flaw was found in the
ethtool_get_regs() function in the Linux kernel's
ethtool IOCTL handler. A local user who has the
CAP_NET_ADMIN capability could use this flaw to cause an
information leak. (CVE-2010-4655, Low)
- An information leak was found in the Linux kernel's
task_show_regs() implementation. On IBM S/390 systems, a
local, unprivileged user could use this flaw to read
/proc/[PID]/status files, allowing them to discover the
CPU register values of processes. (CVE-2011-0710, Low)
This update also fixes several bugs.
The system must be rebooted for this update to take effect.
