Test Kennung:1.3.6.1.4.1.25623.1.0.69154
Kategorie:Red Hat Local Security Checks
Titel:RedHat Security Advisory RHSA-2010:0842
Zusammenfassung:NOSUMMARY
Beschreibung:Description:
The remote host is missing updates announced in
advisory RHSA-2010:0842.

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

This update fixes the following security issues:

* Missing sanity checks in the Intel i915 driver in the Linux kernel could
allow a local, unprivileged user to escalate their privileges.
(CVE-2010-2962, Important)

* compat_alloc_user_space() in the Linux kernel 32/64-bit compatibility
layer implementation was missing sanity checks. This function could be
abused in other areas of the Linux kernel if its length argument can be
controlled from user-space. On 64-bit systems, a local, unprivileged user
could use this flaw to escalate their privileges. (CVE-2010-3081,
Important)

* A buffer overflow flaw in niu_get_ethtool_tcam_all() in the niu Ethernet
driver in the Linux kernel, could allow a local user to cause a denial of
service or escalate their privileges. (CVE-2010-3084, Important)

* A flaw in the IA32 system call emulation provided in 64-bit Linux kernels
could allow a local user to escalate their privileges. (CVE-2010-3301,
Important)

* A flaw in sctp_packet_config() in the Linux kernel's Stream Control
Transmission Protocol (SCTP) implementation could allow a remote attacker
to cause a denial of service. (CVE-2010-3432, Important)

* A missing integer overflow check in snd_ctl_new() in the Linux kernel's
sound subsystem could allow a local, unprivileged user on a 32-bit system
to cause a denial of service or escalate their privileges. (CVE-2010-3442,
Important)

* A flaw was found in sctp_auth_asoc_get_hmac() in the Linux kernel's SCTP
implementation. When iterating through the hmac_ids array, it did not reset
the last id element if it was out of range. This could allow a remote
attacker to cause a denial of service. (CVE-2010-3705, Important)

* A function in the Linux kernel's Reliable Datagram Sockets (RDS) protocol
implementation was missing sanity checks, which could allow a local,
unprivileged user to escalate their privileges. (CVE-2010-3904, Important)

* A flaw in drm_ioctl() in the Linux kernel's Direct Rendering Manager
(DRM) implementation could allow a local, unprivileged user to cause an
information leak. (CVE-2010-2803, Moderate)

* It was found that wireless drivers might not always clear allocated
buffers when handling a driver-specific IOCTL information request. A local
user could trigger this flaw to cause an information leak. (CVE-2010-2955,
Moderate)

* A NULL pointer dereference flaw in ftrace_regex_lseek() in the Linux
kernel's ftrace implementation could allow a local, unprivileged user to
cause a denial of service. Note: The debugfs file system must be mounted
locally to exploit this issue. It is not mounted by default.
(CVE-2010-3079, Moderate)

* A flaw in the Linux kernel's packet writing driver could be triggered
via the PKT_CTRL_CMD_STATUS IOCTL request, possibly allowing a local,
unprivileged user with access to /dev/pktcdvd/control to cause an
information leak. Note: By default, only users in the cdrom group have
access to /dev/pktcdvd/control. (CVE-2010-3437, Moderate)

* A flaw was found in the way KVM (Kernel-based Virtual Machine) handled
the reloading of fs and gs segment registers when they had invalid
selectors. A privileged host user with access to /dev/kvm could use this
flaw to crash the host. (CVE-2010-3698, Moderate)

Red Hat would like to thank Kees Cook for reporting CVE-2010-2962 and
CVE-2010-2803
Ben Hawkes for reporting CVE-2010-3081 and CVE-2010-3301

Dan Rosenberg for reporting CVE-2010-3442, CVE-2010-3705, CVE-2010-3904,
and CVE-2010-3437
and Robert Swiecki for reporting CVE-2010-3079.

This update also fixes several bugs. Documentation for these bug fixes will
be available shortly from the Technical Notes document linked to in the
References section.

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
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
