This update for libxkbcommon to version 0.8.2 fixes the following issues:

- Fix a few NULL-dereferences, out-of-bounds access and undefined behavior in
the XKB text format parser.
- CVE-2018-15853: Endless recursion could have been used by local attackers to
crash xkbcommon users by supplying a crafted keymap file that triggers boolean
negation (bsc#1105832).
- CVE-2018-15854: Unchecked NULL pointer usage could have been used by local
attackers to crash (NULL pointer dereference) the xkbcommon parser by supplying
a crafted keymap file, because geometry tokens were desupported incorrectly
(bsc#1105832).
- CVE-2018-15855: Unchecked NULL pointer usage could have been 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 (bsc#1105832).
- CVE-2018-15856: An infinite loop when reaching EOL unexpectedly could be used
by local attackers to cause a denial of service during parsing of crafted
keymap files (bsc#1105832).
- CVE-2018-15857: An invalid free in ExprAppendMultiKeysymList could have been
used by local attackers to crash xkbcommon keymap parsers or possibly have
unspecified other impact by supplying a crafted keymap file (bsc#1105832).
- CVE-2018-15858: Unchecked NULL pointer usage when handling invalid aliases in
CopyKeyAliasesToKeymap could have been used by local attackers to crash (NULL
pointer dereference) the xkbcommon parser by supplying a crafted keymap file
(bsc#1105832).
- CVE-2018-15859: Unchecked NULL pointer usage when parsing invalid atoms in
ExprResolveLhs could have been used by local attackers to crash (NULL pointer
dereference) the xkbcommon parser by supplying a crafted keymap file, because
lookup failures are mishandled (bsc#1105832).
- CVE-2018-15861: Unchecked NULL pointer usage in ExprResolveLhs could have
been 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 (bsc#1105832).
- CVE-2018-15862: Unchecked NULL pointer usage in LookupModMask could have been
used by local attackers to crash (NULL pointer dereference) the xkbcommon
parser by supplying a crafted keymap file with invalid virtual modifiers
(bsc#1105832).
- CVE-2018-15863: Unchecked NULL pointer usage in ResolveStateAndPredicate
could have been used by local attackers to crash (NULL pointer dereference) the
xkbcommon parser by supplying a crafted keymap file with a no-op modmask
expression (bsc#1105832).
- CVE-2018-15864: Unchecked NULL pointer usage in resolve_keysym could have
been 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 (bsc#1105832).
