CVE-2018-15864 3 Canonical, Redhat, Xkbcommon 4 Ubuntu Linux, Enterprise Linux, Libxkbcommon and 1 more 2024-11-21 N/A
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.
CVE-2018-15863 3 Canonical, Redhat, Xkbcommon 4 Ubuntu Linux, Enterprise Linux, Libxkbcommon and 1 more 2024-11-21 N/A
Unchecked NULL pointer usage in ResolveStateAndPredicate in xkbcomp/compat.c 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 with a no-op modmask expression.
CVE-2018-15862 3 Canonical, Redhat, Xkbcommon 4 Ubuntu Linux, Enterprise Linux, Libxkbcommon and 1 more 2024-11-21 N/A
Unchecked NULL pointer usage in LookupModMask in xkbcomp/expr.c 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 with invalid virtual modifiers.
CVE-2018-15861 3 Canonical, Redhat, Xkbcommon 4 Ubuntu Linux, Enterprise Linux, Libxkbcommon and 1 more 2024-11-21 N/A
Unchecked NULL pointer usage in ExprResolveLhs in xkbcomp/expr.c 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 that triggers an xkb_intern_atom failure.
CVE-2018-15859 3 Canonical, Redhat, Xkbcommon 4 Ubuntu Linux, Enterprise Linux, Libxkbcommon and 1 more 2024-11-21 N/A
Unchecked NULL pointer usage when parsing invalid atoms in ExprResolveLhs in xkbcomp/expr.c 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 lookup failures are mishandled.
CVE-2018-15858 2 Canonical, Xkbcommon 3 Ubuntu Linux, Libxkbcommon, Xkbcommon 2024-11-21 N/A
Unchecked NULL pointer usage when handling invalid aliases in CopyKeyAliasesToKeymap in xkbcomp/keycodes.c in xkbcommon before 0.8.1 could be used by local attackers to crash (NULL pointer dereference) the xkbcommon parser by supplying a crafted keymap file.
CVE-2018-15857 3 Canonical, Redhat, Xkbcommon 4 Ubuntu Linux, Enterprise Linux, Libxkbcommon and 1 more 2024-11-21 N/A
An invalid free in ExprAppendMultiKeysymList in xkbcomp/ast-build.c in xkbcommon before 0.8.1 could be used by local attackers to crash xkbcommon keymap parsers or possibly have unspecified other impact by supplying a crafted keymap file.
CVE-2018-15856 3 Canonical, Redhat, Xkbcommon 3 Ubuntu Linux, Enterprise Linux, Xkbcommon 2024-11-21 N/A
An infinite loop when reaching EOL unexpectedly in compose/parser.c (aka the keymap parser) in xkbcommon before 0.8.1 could be used by local attackers to cause a denial of service during parsing of crafted keymap files.
CVE-2018-15853 3 Canonical, Redhat, Xkbcommon 4 Ubuntu Linux, Enterprise Linux, Libxkbcommon and 1 more 2024-11-21 N/A
Endless recursion exists in xkbcomp/expr.c in xkbcommon and libxkbcommon before 0.8.1, which could be used by local attackers to crash xkbcommon users by supplying a crafted keymap file that triggers boolean negation.
