| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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. | 2.1 |
| 2018-08-25 | CVE-2018-15859 | NULL Pointer Dereference vulnerability in multiple products 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. | 2.1 |
| 2018-08-25 | CVE-2018-15861 | NULL Pointer Dereference vulnerability in multiple products 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. | 2.1 |
| 2018-08-25 | CVE-2018-15862 | NULL Pointer Dereference vulnerability in multiple products 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. | 2.1 |
| 2018-08-25 | CVE-2018-15863 | NULL Pointer Dereference vulnerability in multiple products 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. | 2.1 |
| 2018-08-25 | CVE-2018-15864 | NULL Pointer Dereference vulnerability in multiple products 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. | 2.1 |
| 2018-08-20 | CVE-2018-15594 | Information Exposure vulnerability in multiple products arch/x86/kernel/paravirt.c in the Linux kernel before 4.18.1 mishandles certain indirect calls, which makes it easier for attackers to conduct Spectre-v2 attacks against paravirtual guests. | 2.1 |
| 2018-08-20 | CVE-2018-15572 | The spectre_v2_select_mitigation function in arch/x86/kernel/cpu/bugs.c in the Linux kernel before 4.18.1 does not always fill RSB upon a context switch, which makes it easier for attackers to conduct userspace-userspace spectreRSB attacks. | 2.1 |
| 2018-08-10 | CVE-2018-6556 | Channel and Path Errors vulnerability in multiple products lxc-user-nic when asked to delete a network interface will unconditionally open a user provided path. | 2.1 |
| 2018-08-08 | CVE-2018-14526 | Improper Enforcement of Message Integrity During Transmission in a Communication Channel vulnerability in multiple products An issue was discovered in rsn_supp/wpa.c in wpa_supplicant 2.0 through 2.6. | 3.3 |
