{"id":"RLSA-2021:1804","summary":"Moderate: userspace graphics, xorg-x11, and mesa security, bug fix, and enhancement update","details":"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.\n\nMesa provides a 3D graphics API that is compatible with Open Graphics Library (OpenGL). It also provides hardware-accelerated drivers for many popular graphics chips.\n\nThe 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)\n\nSecurity Fix(es):\n\n* xorg-x11-server: Out-of-bounds access in XkbSetNames function (CVE-2020-14345)\n\n* xorg-x11-server: Integer underflow in the X input extension protocol (CVE-2020-14346)\n\n* xorg-x11-server: Out-of-bounds access in XkbSetMap function (CVE-2020-14360)\n\n* xorg-x11-server: XkbSelectEvents integer underflow privilege escalation vulnerability (CVE-2020-14361)\n\n* xorg-x11-server: XRecordRegisterClients integer underflow privilege escalation vulnerability (CVE-2020-14362)\n\n* libX11: Integer overflow leads to double free in locale handling (CVE-2020-14363)\n\n* xorg-x11-server: XkbSetDeviceInfo heap-based buffer overflow privilege escalation vulnerability (CVE-2020-25712)\n\n* libX11: Heap overflow in the X input method client (CVE-2020-14344)\n\n* xorg-x11-server: Leak of uninitialized heap memory from the X server to clients in AllocatePixmap of dix/pixmap.c (CVE-2020-14347)\n\nFor more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.\n\nAdditional Changes:\n\nFor
