The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2014-04331 advisory.

  - Multiple array index errors in drivers/hid/hid-core.c in the Human Interface Device (HID) subsystem in the     Linux kernel through 3.11 allow physically proximate attackers to execute arbitrary code or cause a denial     of service (heap memory corruption) via a crafted device that provides an invalid Report ID.
    (CVE-2013-2888)

  - The tcp_rcv_state_process function in net/ipv4/tcp_input.c in the Linux kernel before 3.2.24 allows remote     attackers to cause a denial of service (kernel resource consumption) via a flood of SYN+FIN TCP packets, a     different vulnerability than CVE-2012-2663. (CVE-2012-6638)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

This plugin has been deprecated as it is a duplicate of oraclelinux_ELSA-2014-0433-1.nasl (plugin ID 73720).

Updated kernel packages that fix two security issues, three bugs, and add one enhancement are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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

* A flaw was found in the way the Linux kernel's TCP/IP protocol suite implementation handled TCP packets with both the SYN and FIN flags set. A remote attacker could use this flaw to consume an excessive amount of resources on the target system, potentially resulting in a denial of service. (CVE-2012-6638, Moderate)

* A flaw was found in the way the Linux kernel handled HID (Human Interface Device) reports with an out-of-bounds Report ID. An attacker with physical access to the system could use this flaw to crash the system or, potentially, escalate their privileges on the system.
(CVE-2013-2888, Moderate)

This update also fixes the following bugs :

* A previous change to the sunrpc code introduced a race condition between the rpc_wake_up_task() and rpc_wake_up_status() functions. A race between threads operating on these functions could result in a deadlock situation, subsequently triggering a 'soft lockup' event and rendering the system unresponsive. This problem has been fixed by re-ordering tasks in the RPC wait queue. (BZ#1073731)

* Running a process in the background on a GFS2 file system could sometimes trigger a glock recursion error that resulted in a kernel panic. This happened when a readpage operation attempted to take a glock that had already been held by another function. To prevent this error, GFS2 now verifies whether the glock is already held when performing the readpage operation. (BZ#1073953)

* A previous patch backport to the IUCV (Inter User Communication Vehicle) code was incomplete. Consequently, when establishing an IUCV connection, the kernel could, under certain circumstances, dereference a NULL pointer, resulting in a kernel panic. A patch has been applied to correct this problem by calling the proper function when removing IUCV paths. (BZ#1077045)

In addition, this update adds the following enhancement :

* The lpfc driver had a fixed timeout of 60 seconds for SCSI task management commands. With this update, the lpfc driver enables the user to set this timeout within the range from 5 to 180 seconds. The timeout can be changed by modifying the 'lpfc_task_mgmt_tmo' parameter for the lpfc driver. (BZ#1073123)

All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add this enhancement. The system must be rebooted for this update to take effect.

Updated kernel packages that fix three security issues and two bugs are now available for Red Hat Enterprise Linux 5.9 Extended Update Support.

The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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

* A flaw was found in the way the Linux kernel's floppy driver handled user space provided data in certain error code paths while processing FDRAWCMD IOCTL commands. A local user with write access to /dev/fdX could use this flaw to free (using the kfree() function) arbitrary kernel memory. (CVE-2014-1737, Important)

* It was found that the Linux kernel's floppy driver leaked internal kernel memory addresses to user space during the processing of the FDRAWCMD IOCTL command. A local user with write access to /dev/fdX could use this flaw to obtain information about the kernel heap arrangement. (CVE-2014-1738, Low)

Note: A local user with write access to /dev/fdX could use these two flaws (CVE-2014-1737 in combination with CVE-2014-1738) to escalate their privileges on the system.

* A flaw was found in the way the Linux kernel's TCP/IP protocol suite implementation handled TCP packets with both the SYN and FIN flags set. A remote attacker could use this flaw to consume an excessive amount of resources on the target system, potentially resulting in a denial of service. (CVE-2012-6638, Moderate)

Red Hat would like to thank Matthew Daley for reporting CVE-2014-1737 and CVE-2014-1738.

This update also fixes the following bugs :

* While under heavy load, some Fibre Channel storage devices, such as Hitachi and HP Open-V series, can send a logout (LOGO) message to the host system. However, due to a bug in the lpfc driver, this could result in a loss of active paths to the storage and the paths could not be recovered without manual intervention. This update corrects the lpfc driver to ensure automatic recovery of the lost paths to the storage in this scenario. (BZ#1096060)

* A bug in the futex system call could result in an overflow when passing a very large positive timeout. As a consequence, the FUTEX_WAIT operation did not work as intended and the system call was timing out immediately. A backported patch fixes this bug by limiting very large positive timeouts to the maximal supported value.
(BZ#1091831)
