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

high Nessus Plugin ID 61035

Language:

Synopsis

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

Description

Security fixes :

 - An integer overflow flaw in ib_uverbs_poll_cq() could allow a local, unprivileged user to cause a denial of service or escalate their privileges. (CVE-2010-4649, Important)

 - An integer signedness flaw in drm_modeset_ctl() could allow a local, unprivileged user to cause a denial of service or escalate their privileges. (CVE-2011-1013, Important)

 - The Radeon GPU drivers in the Linux kernel were missing sanity checks for the Anti Aliasing (AA) resolve register values which could allow a local, unprivileged user to cause a denial of service or escalate their privileges on systems using a graphics card from the ATI Radeon R300, R400, or R500 family of cards.
 (CVE-2011-1016, Important)

 - A flaw in dccp_rcv_state_process() could allow a remote attacker to cause a denial of service, even when the socket was already closed. (CVE-2011-1093, Important)

 - A flaw in the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation could allow a remote attacker to cause a denial of service if the sysctl 'net.sctp.addip_enable' and 'auth_enable' variables were turned on (they are off by default). (CVE-2011-1573, Important)

 - A memory leak in the inotify_init() system call. In some cases, it could leak a group, which could allow a local, unprivileged user to eventually cause a denial of service. (CVE-2010-4250, Moderate)

 - A missing validation of a null-terminated string data structure element in bnep_sock_ioctl() could allow a local user to cause an information leak or a denial of service. (CVE-2011-1079, Moderate)

 - An information leak in bcm_connect() in the Controller Area Network (CAN) Broadcast Manager implementation could allow a local, unprivileged user to leak kernel mode addresses in '/proc/net/can-bcm'. (CVE-2010-4565, Low)

 - A flaw was found in the Linux kernel's Integrity Measurement Architecture (IMA) implementation. When SELinux was disabled, adding an IMA rule which was supposed to be processed by SELinux would cause ima_match_rules() to always succeed, ignoring any remaining rules. (CVE-2011-0006, Low)

 - A missing initialization flaw in the XFS file system implementation could lead to an information leak.
 (CVE-2011-0711, Low)

 - Buffer overflow flaws in snd_usb_caiaq_audio_init() and snd_usb_caiaq_midi_init() could allow a local, unprivileged user with access to a Native Instruments USB audio device to cause a denial of service or escalate their privileges. (CVE-2011-0712, Low)

 - The start_code and end_code values in '/proc/[pid]/stat' were not protected. In certain scenarios, this flaw could be used to defeat Address Space Layout Randomization (ASLR). (CVE-2011-0726, Low)

 - A flaw in dev_load() could allow a local user who has the CAP_NET_ADMIN capability to load arbitrary modules from '/lib/modules/', instead of only netdev modules.
 (CVE-2011-1019, Low)

 - A flaw in ib_uverbs_poll_cq() could allow a local, unprivileged user to cause an information leak.
 (CVE-2011-1044, Low)

 - A missing validation of a null-terminated string data structure element in do_replace() could allow a local user who has the CAP_NET_ADMIN capability to cause an information leak. (CVE-2011-1080, Low)

This update also fixes various bugs.

This update also adds an enhancement.

 - This update provides VLAN null tagging support (VLAN ID 0 can be used in tags).

The system must be rebooted for this update to take effect.

Solution

Update the affected packages.
