RHEL 5 : kernel (RHSA-2010:0839)

medium Nessus Plugin ID 50537

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for kernel.

Description

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2010:0839 advisory.

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

This update fixes the following security issues:

* A NULL pointer dereference flaw was found in the io_submit_one() function in the Linux kernel asynchronous I/O implementation. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2010-3066, Moderate)

* A flaw was found in the xfs_ioc_fsgetxattr() function in the Linux kernel XFS file system implementation. A data structure in xfs_ioc_fsgetxattr() was not initialized properly before being copied to user-space. A local, unprivileged user could use this flaw to cause an information leak.
(CVE-2010-3078, Moderate)

* The exception fixup code for the __futex_atomic_op1, __futex_atomic_op2, and futex_atomic_cmpxchg_inatomic() macros replaced the LOCK prefix with a NOP instruction. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2010-3086, Moderate)

* A flaw was found in the tcf_act_police_dump() function in the Linux kernel network traffic policing implementation. A data structure in tcf_act_police_dump() was not initialized properly before being copied to user-space. A local, unprivileged user could use this flaw to cause an information leak. (CVE-2010-3477, Moderate)

* A missing upper bound integer check was found in the sys_io_submit() function in the Linux kernel asynchronous I/O implementation. A local, unprivileged user could use this flaw to cause an information leak.
(CVE-2010-3067, Low)

Red Hat would like to thank Tavis Ormandy for reporting CVE-2010-3066, CVE-2010-3086, and CVE-2010-3067, and Dan Rosenberg for reporting CVE-2010-3078.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Solution

Update the RHEL kernel package based on the guidance in RHSA-2010:0839.
