RHEL 8 : userspace graphics, xorg-x11, and mesa (RHSA-2021:1804)

high Nessus Plugin ID 149659

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:1804 advisory.

X.Org is an open-source implementation of the X Window System. It provides the basic low-level functionality that full-fledged graphical user interfaces are designed upon.

Mesa provides a 3D graphics API that is compatible with Open Graphics Library (OpenGL). It also provides hardware-accelerated drivers for many popular graphics chips.

The following packages have been upgraded to a later upstream version: egl-wayland (1.1.5), libdrm (2.4.103), libglvnd (1.3.2), libinput (1.16.3), libwacom (1.6), mesa (20.3.3), xorg-x11-server (1.20.10).
(BZ#1878160, BZ#1886648, BZ#1887654, BZ#1887655)

Security Fix(es):

* xorg-x11-server: Out-of-bounds access in XkbSetNames function (CVE-2020-14345)

* xorg-x11-server: Integer underflow in the X input extension protocol (CVE-2020-14346)

* xorg-x11-server: Out-of-bounds access in XkbSetMap function (CVE-2020-14360)

* xorg-x11-server: XkbSelectEvents integer underflow privilege escalation vulnerability (CVE-2020-14361)

* xorg-x11-server: XRecordRegisterClients integer underflow privilege escalation vulnerability (CVE-2020-14362)

* libX11: Integer overflow leads to double free in locale handling (CVE-2020-14363)

* xorg-x11-server: XkbSetDeviceInfo heap-based buffer overflow privilege escalation vulnerability (CVE-2020-25712)

* libX11: Heap overflow in the X input method client (CVE-2020-14344)

* xorg-x11-server: Leak of uninitialized heap memory from the X server to clients in AllocatePixmap of dix/pixmap.c (CVE-2020-14347)
