|---|---|---|---|
| 2018-08-25 | CVE-2018-15858 | NULL Pointer Dereference vulnerability in multiple products 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. | 5.5 |
| 2018-08-25 | CVE-2018-15857 | Use After Free vulnerability in multiple products 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. | 7.8 |
| 2018-08-25 | CVE-2018-15856 | Infinite Loop vulnerability in multiple products 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. | 5.5 |
| 2018-08-25 | CVE-2018-15855 | NULL Pointer Dereference vulnerability in multiple products Unchecked NULL pointer usage 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, because the XkbFile for an xkb_geometry section was mishandled. | 5.5 |
| 2018-08-25 | CVE-2018-15854 | NULL Pointer Dereference vulnerability in multiple products Unchecked NULL pointer usage 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, because geometry tokens were desupported incorrectly. | 5.5 |
| 2018-08-25 | CVE-2018-15853 | Resource Exhaustion vulnerability in multiple products 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. | 5.5 |
