| CVE-2018-15864 | 2 Canonical, Xkbcommon | 3 Ubuntu Linux, Libxkbcommon, Xkbcommon | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
| 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 | 2 Canonical, Xkbcommon | 3 Ubuntu Linux, Libxkbcommon, Xkbcommon | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
| 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 | 2 Canonical, Xkbcommon | 3 Ubuntu Linux, Libxkbcommon, Xkbcommon | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
| 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 | 2 Canonical, Xkbcommon | 3 Ubuntu Linux, Libxkbcommon, Xkbcommon | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
| 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 | 2 Canonical, Xkbcommon | 3 Ubuntu Linux, Libxkbcommon, Xkbcommon | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
| 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 | 2.1 LOW | 5.5 MEDIUM |
| 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 | 2 Canonical, Xkbcommon | 3 Ubuntu Linux, Libxkbcommon, Xkbcommon | 2024-11-21 | 4.6 MEDIUM | 7.8 HIGH |
| 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 | 2 Canonical, Xkbcommon | 2 Ubuntu Linux, Xkbcommon | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
| 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 | 2 Canonical, Xkbcommon | 3 Ubuntu Linux, Libxkbcommon, Xkbcommon | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
| 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. | |||||
