ALSA-2021:1804 — Moderate: userspace graphics, xorg-x11, and mesa security, bug fix, and enhancement update

Affected: AlmaLinux:8: libglvnd, AlmaLinux:8: libglvnd-core-devel, AlmaLinux:8: libglvnd-devel, AlmaLinux:8: libglvnd-egl, AlmaLinux:8: libglvnd-gles, AlmaLinux:8: libglvnd-glx, AlmaLinux:8: libglvnd-opengl, AlmaLinux:8: libinput-devel, AlmaLinux:8: libwacom-devel, AlmaLinux:8: mesa-libOSMesa-devel and 4 more

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)

A flaw was found in the way xserver memory was not properly initialized. This could leak parts of server memory to the X client. In cases where Xorg server runs with elevated privileges, this could result in possible ASLR bypass. Xorg-server before version 1.20.9 is vulnerable.
