Synopsis :

Description :

From Red Hat Security Advisory 2017:1865 :

An update is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The X11 (Xorg) libraries provide library routines that are used within
all X Window applications.

The following packages have been upgraded to a later upstream version:
libX11 (1.6.5), libXaw (1.0.13), libXdmcp (1.1.2), libXfixes (5.0.3),
libXfont (1.5.2), libXi (1.7.9), libXpm (3.5.12), libXrandr (1.5.1),
libXrender (0.9.10), libXt (1.1.5), libXtst (1.2.3), libXv (1.0.11),
libXvMC (1.0.10), libXxf86vm (1.1.4), libdrm (2.4.74), libepoxy
(1.3.1), libevdev (1.5.6), libfontenc (1.1.3), libvdpau (1.1.1),
libwacom (0.24), libxcb (1.12), libxkbfile (1.0.9), mesa (17.0.1),
mesa-private-llvm (3.9.1), xcb-proto (1.12), xkeyboard-config (2.20),
xorg-x11-proto-devel (7.7). (BZ#1401667, BZ#1401668, BZ#1401669,

Security Fix(es) :

* An integer overflow flaw leading to a heap-based buffer overflow was
found in libXpm. An attacker could use this flaw to crash an
application using libXpm via a specially crafted XPM file.
(CVE-2016-10164)

* It was discovered that libXdmcp used weak entropy to generate
session keys. On a multi-user system using xdmcp, a local attacker
could potentially use information available from the process list to
brute force the key, allowing them to hijack other users' sessions.
(CVE-2017-2625)

* It was discovered that libICE used a weak entropy to generate keys.
A local attacker could potentially use this flaw for session hijacking
using the information available from the process list. (CVE-2017-2626)

Red Hat would like to thank Eric Sesterhenn (X41 D-Sec GmbH) for
reporting CVE-2017-2625 and CVE-2017-2626.
