F5 Networks BIG-IP : Linux kernel vulnerability (K08440897)

medium Nessus Plugin ID 93255

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

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)

Impact

A local unprivileged user may be able to leak kernel memory to user space or cause a denial of service (DoS).

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K08440897.
