Oracle Linux 6 : Unbreakable Enterprise kernel (ELSA-2014-3021)

medium Nessus Plugin ID 73959

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-2014-3021 advisory.

- The aac_compat_ioctl function in drivers/scsi/aacraid/linit.c in the Linux kernel before 3.11.8 does not require the CAP_SYS_RAWIO capability, which allows local users to bypass intended access restrictions via a crafted ioctl call. (CVE-2013-6383)

- drivers/vhost/net.c in the Linux kernel before 3.13.10, when mergeable buffers are disabled, does not properly validate packet lengths, which allows guest OS users to cause a denial of service (memory corruption and host OS crash) or possibly gain privileges on the host OS via crafted packets, related to the handle_rx and get_rx_bufs functions. (CVE-2014-0077)

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.
