  "details" : [ "An issue was discovered in dbus >= 1.3.0 before 1.12.18. The DBusServer in libdbus, as used in dbus-daemon, leaks file descriptors when a message exceeds the per-message file descriptor limit. A local attacker with access to the D-Bus system bus or another system service's private AF_UNIX socket could use this to make the system service reach its file descriptor limit, denying service to subsequent D-Bus clients.", "An uncontrolled resource consumption vulnerability was discovered in D-Bus. The DBusServer leaks file descriptors when a message exceeds the per-message file descriptor limit. This flaw allows a local attacker with access to the D-Bus system bus or another system service's private AF_UNIX socket, to make the system service reach its file descriptor limit, denying service to subsequent D-Bus clients. As a result, the system may become unusable for other users, and some services may stop working. The highest threat from this vulnerability is to system availability." ],
  "statement" : "This issue did not affect the versions of dbus as shipped with Red Hat Enterprise Linux 5, and 6 as they did not include the vulnerable code.",
