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)
This update also fixes several bugs.
The system must be rebooted for this update to take effect.
