Details

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- -p1 %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 the Big Requests extension. The request length is multiplied by 4 before checking against the maximum allowed size, potentially causing an integer overflow and bypassing the size check.(CVE-2025-49176)
