CVE History

CVE	Published	CVSS v3	CVSS v2
CVE-2018-15858 ↗	Aug 25, 2018Saturday, 25 August 2018, 21:29	—	2.1 LOW
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-2018-15859 ↗	Aug 25, 2018Saturday, 25 August 2018, 21:29	—	2.1 LOW
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-2018-15861 ↗	Aug 25, 2018Saturday, 25 August 2018, 21:29	—	2.1 LOW
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-2018-15862 ↗	Aug 25, 2018Saturday, 25 August 2018, 21:29	—	2.1 LOW
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-2018-15863 ↗	Aug 25, 2018Saturday, 25 August 2018, 21:29	—	2.1 LOW
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-2018-15864 ↗	Aug 25, 2018Saturday, 25 August 2018, 21:29	—	2.1 LOW
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-2018-15853 ↗	Aug 25, 2018Saturday, 25 August 2018, 21:29	—	2.1 LOW
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.
CVE-2018-15854 ↗	Aug 25, 2018Saturday, 25 August 2018, 21:29	—	2.1 LOW
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.
CVE-2018-15855 ↗	Aug 25, 2018Saturday, 25 August 2018, 21:29	—	2.1 LOW
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.
CVE-2018-15856 ↗	Aug 25, 2018Saturday, 25 August 2018, 21:29	—	2.1 LOW
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-2018-15857 ↗	Aug 25, 2018Saturday, 25 August 2018, 21:29	—	4.6 MEDIUM
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.
