An update for xorg-x11-server-xwayland is now available for openEuler-22.03-LTS-SP3 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2024-2041 Final 1.0 1.0 2024-08-23 Initial 2024-08-23 2024-08-23 openEuler SA Tool V1.0 2024-08-23 xorg-x11-server-xwayland security update An update for xorg-x11-server-xwayland is now available for openEuler-22.03-LTS-SP3 Xwayland is an X server for running X clients under Wayland. %package devel Summary: Development package Requires: pkgconfig %description devel The development package provides the developmental files which are necessary for developing Wayland compositors using Xwayland. %prep %autosetup -n xwayland- %build %meson \ -Dxwayland_eglstream=true \ -Ddefault_font_path="catalogue:/etc/X11/fontpath.d,built-ins" \ -Dbuilder_string="Build ID: -" \ -Dxkb_output_dir=/lib/xkb \ -Dxcsecurity=true \ -Dglamor=true \ -Ddri3=true %meson_build Security Fix(es): A flaw was found in xorg-server. Querying or changing XKB button actions such as moving from a touchpad to a mouse can result in out-of-bounds memory reads and writes. This may allow local privilege escalation or possible remote code execution in cases where X11 forwarding is involved.(CVE-2023-6377) A use-after-free vulnerability was found in the ProcRenderAddGlyphs() function of Xorg servers. This issue occurs when AllocateGlyph() is called to store new glyphs sent by the client to the X server, potentially resulting in multiple entries pointing to the same non-refcounted glyphs. Consequently, ProcRenderAddGlyphs() may free a glyph, leading to a use-after-free scenario when the same glyph pointer is subsequently accessed. This flaw allows an authenticated attacker to execute arbitrary code on the system by sending a specially crafted request.(CVE-2024-31083) An update for xorg-x11-server-xwayland is now available for openEuler-22.03-LTS-SP3. openEuler Security has rated this update as having a security impact of high.
