shield Security update for libxkbcommon
SUSE-SLE-Module-Basesystem-15-2018-2620

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).
