Scientific Linux Security Update : kernel on SL6.x i386/x86_64

High Nessus Plugin ID 61012

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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.
(CVE-2011-0521, Important)

- 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.
(CVE-2011-0695, Important)

- 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.
(CVE-2010-4656, Moderate)

- 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 (CVE-2011-0716, Moderate)

- 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.
