Oracle Linux 6 : kernel (ELSA-2014-0771)

medium Nessus Plugin ID 76155

Synopsis

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

Description

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2014-0771 advisory.

- The futex_requeue function in kernel/futex.c in the Linux kernel through 3.14.5 does not ensure that calls have two different futex addresses, which allows local users to gain privileges via a crafted FUTEX_REQUEUE command that facilitates unsafe waiter modification. (CVE-2014-3153)

- The raw_cmd_copyin function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly handle error conditions during processing of an FDRAWCMD ioctl call, which allows local users to trigger kfree operations and gain privileges by leveraging write access to a /dev/fd device. (CVE-2014-1737)

- The raw_cmd_copyout function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly restrict access to certain pointers during processing of an FDRAWCMD ioctl call, which allows local users to obtain sensitive information from kernel heap memory by leveraging write access to a /dev/fd device. (CVE-2014-1738)

- The lbs_debugfs_write function in drivers/net/wireless/libertas/debugfs.c in the Linux kernel through 3.12.1 allows local users to cause a denial of service (OOPS) by leveraging root privileges for a zero- length write operation. (CVE-2013-6378)

- The __do_follow_link function in fs/namei.c in the Linux kernel before 2.6.33 does not properly handle the last pathname component during use of certain filesystems, which allows local users to cause a denial of service (incorrect free operations and system crash) via an open system call. (CVE-2014-0203)

- The security_context_to_sid_core function in security/selinux/ss/services.c in the Linux kernel before 3.13.4 allows local users to cause a denial of service (system crash) by leveraging the CAP_MAC_ADMIN capability to set a zero-length security context. (CVE-2014-1874)

- arch/s390/kernel/head64.S in the Linux kernel before 3.13.5 on the s390 platform does not properly handle attempted use of the linkage stack, which allows local users to cause a denial of service (system crash) by executing a crafted instruction. (CVE-2014-2039)

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.
