Test ID:1.3.6.1.4.1.25623.1.0.870632
Category:Red Hat Local Security Checks
Title:RedHat Update for kernel RHSA-2011:0498-01
Summary:The remote host is missing an update for the 'kernel'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'kernel'
package(s) announced via the referenced advisory.

Vulnerability Insight:
The kernel packages contain the Linux kernel, the core of any Linux
operating system.

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 l ...
