CVE-2018-15854

The CVE-2018-15854 issue affects libxkbcommon (and related xorg/libX11 components). The root cause is unchecked NULL pointer usage in xkbcommon before 0.8.1, enabling a local attacker to crash the xkbcommon parser via a crafted keymap file (null pointer dereference). Several connected advisories ...

CVE-2018-15855

CVE-2018-15855 : Unchecked NULL pointer usage in libxkbcommon before 0.8.1 can crash the xkbcommon parser when processing a crafted keymap file, due to mishandling of the XkbFile for an xkb_geometry section. Impact is local and leads to denial of service via crash; exploitation requires local acc...

CVE-2018-15853

CVE-2018-15853 – xkbcommon/xkbcomp crash due to endless recursion . A vulnerability in libxkbcommon (and xkbcomp) before 0.8.1 allows a local attacker to crash a user via a specially crafted keymap file that triggers boolean negation in xkbcomp/expr.c. The issue is a local denial of service with ...
