RHEL 6 : kernel (RHSA-2011:0007)

high Nessus Plugin ID 51500

Language:

Synopsis

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

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2011:0007 advisory.

* Buffer overflow in eCryptfs. When /dev/ecryptfs has world writable permissions (which it does not, by default, on Red Hat Enterprise Linux 6), a local, unprivileged user could use this flaw to cause a denial of service or possibly escalate their privileges. (CVE-2010-2492, Important)

* Integer overflow in the RDS protocol implementation could allow a local, unprivileged user to cause a denial of service or escalate their privileges. (CVE-2010-3865, Important)

* Missing boundary checks in the PPP over L2TP sockets implementation could allow a local, unprivileged user to cause a denial of service or escalate their privileges. (CVE-2010-4160, Important)

* NULL pointer dereference in the igb driver. If both Single Root I/O Virtualization (SR-IOV) and promiscuous mode were enabled on an interface using igb, it could result in a denial of service when a tagged VLAN packet is received on that interface. (CVE-2010-4263, Important)

* Missing initialization flaw in the XFS file system implementation, and in the network traffic policing implementation, could allow a local, unprivileged user to cause an information leak. (CVE-2010-3078, CVE-2010-3477, Moderate)

* NULL pointer dereference in the Open Sound System compatible sequencer driver could allow a local, unprivileged user with access to /dev/sequencer to cause a denial of service. /dev/sequencer is only accessible to root and users in the audio group by default. (CVE-2010-3080, Moderate)

* Flaw in the ethtool IOCTL handler could allow a local user to cause an information leak. (CVE-2010-3861, Moderate)

* Flaw in bcm_connect() in the Controller Area Network (CAN) Broadcast Manager. On 64-bit systems, writing the socket address may overflow the procname character array. (CVE-2010-3874, Moderate)

* Flaw in the module for monitoring the sockets of INET transport protocols could allow a local, unprivileged user to cause a denial of service. (CVE-2010-3880, Moderate)

* Missing boundary checks in the block layer implementation could allow a local, unprivileged user to cause a denial of service. (CVE-2010-4162, CVE-2010-4163, CVE-2010-4668, Moderate)

* NULL pointer dereference in the Bluetooth HCI UART driver could allow a local, unprivileged user to cause a denial of service. (CVE-2010-4242, Moderate)

* Flaw in the Linux kernel CPU time clocks implementation for the POSIX clock interface could allow a local, unprivileged user to cause a denial of service. (CVE-2010-4248, Moderate)

* Flaw in the garbage collector for AF_UNIX sockets could allow a local, unprivileged user to trigger a denial of service. (CVE-2010-4249, Moderate)

* Missing upper bound integer check in the AIO implementation could allow a local, unprivileged user to cause an information leak. (CVE-2010-3067, Low)

* Missing initialization flaws could lead to information leaks.
(CVE-2010-3298, 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-2010-4081, CVE-2010-4082, CVE-2010-4083, CVE-2010-4158, Low)

* Missing initialization flaw in KVM could allow a privileged host user with access to /dev/kvm to cause an information leak. (CVE-2010-4525, Low)

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-2011:0007.
