CentOS Errata and Security Advisory CESA-2017:1865
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, BZ#1401670, BZ#1401671, BZ#1401672, BZ#1401673, BZ#1401675, BZ#1401676, BZ#1401677, BZ#1401678, BZ#1401679, BZ#1401680, BZ#1401681, BZ#1401682, BZ#1401683, BZ#1401685, BZ#1401690, BZ#1401752, BZ#1401753, BZ#1401754, BZ#1402560, BZ#1410477, BZ#1411390, BZ#1411392, BZ#1411393, BZ#1411452, BZ#1420224)
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.
