The Linux Kernel was updated to fix various security issues and bugs.

Main security issues fixed :

A security issue in the tty layer that was fixed that could be used by local attackers for code execution (CVE-2014-0196).

Two security issues in the floppy driver were fixed that could be used by local attackers on machines with the floppy to crash the kernel or potentially execute code in the kernel (CVE-2014-1737 CVE-2014-1738).

Other security issues and bugs that were fixed :

  - netfilter: nf_nat: fix access to uninitialized buffer in     IRC NAT helper (bnc#860835 CVE-2014-1690).

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-002409 advisory.

    The sctp_sf_do_5_1D_ce function in net/sctp/sm_statefuns.c in the Linux kernel through 3.13.6 does not     validate certain auth_enable and auth_capable fields before making an sctp_sf_authenticate call, which     allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via an     SCTP handshake with a modified INIT chunk and a crafted AUTH chunk before a COOKIE_ECHO chunk.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

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

Updated kernel packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 6.4 Extended Update Support.

The Red Hat Security Response Team has rated this update as having Important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2014:0520 advisory.

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

    * A flaw was found in the way the Linux kernel processed an authenticated     COOKIE_ECHO chunk during the initialization of an SCTP connection. A remote     attacker could use this flaw to crash the system by initiating a specially     crafted SCTP handshake in order to trigger a NULL pointer dereference on     the system. (CVE-2014-0101, Important)

    * A race condition flaw, leading to heap-based buffer overflows, was found     in the way the Linux kernel's N_TTY line discipline (LDISC) implementation     handled concurrent processing of echo output and TTY write operations     originating from user space when the underlying TTY driver was PTY.
    An unprivileged, local user could use this flaw to crash the system or,     potentially, escalate their privileges on the system. (CVE-2014-0196,     Important)

    Red Hat would like to thank Nokia Siemens Networks for reporting     CVE-2014-0101.

    This update also fixes the following bug:

    * Prior to this update, a guest-provided value was used as the head length     of the socket buffer allocated on the host. If the host was under heavy     memory load and the guest-provided value was too large, the allocation     could have failed, resulting in stalls and packet drops in the guest's Tx     path. With this update, the guest-provided value has been limited to a     reasonable size so that socket buffer allocations on the host succeed     regardless of the memory load on the host, and guests can send packets     without experiencing packet drops or stalls. (BZ#1092349)

    All kernel users are advised to 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.

Red Hat would like to thank Nokia Siemens Networks for reporting this issue.

This update also fixes the following bug :

* Due to an incorrect call of the weak-modules script in the kernel spec file, the weak-modules directory was removed from the system when removing or upgrading certain kernel packages related to weak-modules, such as kernel-debug. With this update, the weak-modules call in the kernel spec file has been corrected, and the script now preserves the weak-modules directory on the system in this scenario. (BZ#1076599)

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