Synopsis

The remote Oracle Linux host is missing a security update.

Description

The remote Oracle Linux 7 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2014-0678 advisory.

- The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through 3.14.3 does not properly manage tty driver access in the LECHO & !OPOST case, which allows local users to cause a denial of service (memory corruption and system crash) or gain privileges by triggering a race condition involving read and write operations with long strings. (CVE-2014-0196)

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.
