Oracle Linux 5 / 6 : unbreakable enterprise kernel (ELSA-2013-2542)

medium Nessus Plugin ID 69509
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

The remote Oracle Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2013-2542 advisory.

- The Bluetooth protocol stack in the Linux kernel before 3.6 does not properly initialize certain structures, which allows local users to obtain sensitive information from kernel stack memory via a crafted application that targets the (1) L2CAP or (2) HCI implementation. (CVE-2012-6544)

- The sctp_sf_do_5_2_4_dupcook function in net/sctp/sm_statefuns.c in the SCTP implementation in the Linux kernel before 3.8.5 does not properly handle associations during the processing of a duplicate COOKIE ECHO chunk, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via crafted SCTP traffic. (CVE-2013-2206)

- The ip6_sk_dst_check function in net/ipv6/ip6_output.c in the Linux kernel before 3.10 allows local users to cause a denial of service (system crash) by using an AF_INET6 socket for a connection to an IPv4 interface. (CVE-2013-2232)

- The key_notify_policy_flush function in net/key/af_key.c in the Linux kernel before 3.9 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel heap memory by reading a broadcast message from the notify_policy interface of an IPSec key_socket.
(CVE-2013-2237)

- Format string vulnerability in the register_disk function in block/genhd.c in the Linux kernel through 3.9.4 allows local users to gain privileges by leveraging root access and writing format string specifiers to /sys/module/md_mod/parameters/new_array in order to create a crafted /dev/md device name.
(CVE-2013-2851)

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

Solution

Update the affected packages.
