medium Nessus Plugin ID 90113

Synopsis

The remote Oracle Linux host is missing a security update.

Description

The remote Oracle Linux 6 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2016-0494 advisory.

 - The (1) pipe_read and (2) pipe_write implementations in fs/pipe.c in a certain Linux kernel backport in the linux package before 3.2.73-2+deb7u3 on Debian wheezy and the kernel package before 3.10.0-229.26.2 on Red Hat Enterprise Linux (RHEL) 7.1 do not properly consider the side effects of failed
 __copy_to_user_inatomic and __copy_from_user_inatomic calls, which allows local users to cause a denial of service (system crash) or possibly gain privileges via a crafted application, aka an I/O vector array overrun. NOTE: this vulnerability exists because of an incorrect fix for CVE-2015-1805. (CVE-2016-0774)

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.
