| Descripción: | Description:
The remote host is missing updates announced in
advisory RHSA-2010:0958.
The kernel-rt packages contain the Linux kernel, the core of any Linux
operating system.
Security fixes:
* 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)
* 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 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)
* Missing sanity checks in setup_arg_pages() in the Linux kernel. When
making the size of the argument and environment area on the stack very
large, it could trigger a BUG_ON(), resulting in a local denial of service.
(CVE-2010-3858, Moderate)
* A flaw in ethtool_get_rxnfc() in the Linux kernel's ethtool IOCTL
handler. When it is called with a large info.rule_cnt, it could allow a
local user to cause an information leak. (CVE-2010-3861, Moderate)
* A flaw in bcm_connect() in the Linux kernel's Controller Area Network
(CAN) Broadcast Manager. On 64-bit systems, writing the socket address may
overflow the procname character array. (CVE-2010-3874, Moderate)
* A flaw in inet_csk_diag_dump() in the Linux kernel's module for
monitoring the sockets of INET transport protocols. By sending a netlink
message with certain bytecode, a local, unprivileged user could cause a
denial of service. (CVE-2010-3880, Moderate)
* Missing sanity checks in gdth_ioctl_alloc() in the gdth driver in the
Linux kernel, could allow a local user with access to /dev/gdth on a
64-bit system to cause a denial of service or escalate their privileges.
(CVE-2010-4157, Moderate)
* A use-after-free flaw in the mprotect() system call could allow a local,
unprivileged user to cause a local denial of service. (CVE-2010-4169,
Moderate)
* Missing initialization flaws in the Linux kernel could lead to
information leaks. (CVE-2010-3876, CVE-2010-4072, CVE-2010-4073,
CVE-2010-4074, CVE-2010-4075, CVE-2010-4077, CVE-2010-4079, CVE-2010-4080,
CVE-2010-4082, CVE-2010-4083, CVE-2010-4158, Low)
