dbus: Possibility of symlink attack in /tmp during compilation
The configure script in D-Bus (aka DBus) 1.2.x before 1.2.28 allows local users to overwrite arbitrary files via a symlink attack on an unspecified file in /tmp/.
The configure script in D-Bus (aka DBus) 1.2.x before 1.2.28 allows local users to overwrite arbitrary files via a symlink attack on an unspecified file in /tmp/.
The dbus_g_proxy_manager_filter function in dbus-gproxy in Dbus-glib before 0.100.1 does not properly verify the sender of NameOwnerChanged signals, which allows local users to gain privileges via a spoofed signal.
The _dbus_printf_string_upper_bound function in dbus/dbus-sysdeps-unix.c in D-Bus (aka DBus) 1.4.x before 1.4.26, 1.6.x before 1.6.12, and 1.7.x before 1.7.4 allows local users to cause a denial of service (service crash) via a crafted message.
The _dbus_header_byteswap function in dbus-marshal-header.c in D-Bus (aka DBus) 1.2.x before 1.2.28, 1.4.x before 1.4.12, and 1.5.x before 1.5.4 does not properly handle a non-native byte order, which allows local users to cause a denial of service (connection loss), obtain potentially sensitive information, or conduct unspecified state-modification attacks via crafted messages.
A use-after-free flaw was found in D-Bus Development branch <= 1.13.16, dbus-1.12.x stable branch <= 1.12.18, and dbus-1.10.x and older branches <= 1.10.30 when a system has multiple usernames sharing the same UID. When a set of policy rules references these usernames, D-Bus may free some memory in the heap, which is still used by data structures necessary for the other usernames sharing the UID, possibly leading to a crash or other undefined behaviors
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.
