DATE CVE VULNERABILITY TITLE RISK
2018-08-25 CVE-2018-15864 NULL Pointer Dereference vulnerability in multiple products
Unchecked NULL pointer usage in resolve_keysym in xkbcomp/parser.y in xkbcommon before 0.8.2 could be used by local attackers to crash (NULL pointer dereference) the xkbcommon parser by supplying a crafted keymap file, because a map access attempt can occur for a map that was never created.
