CVE-2009-1189 1 Freedesktop 1 Dbus 2023-02-12 3.6 LOW N/A
The _dbus_validate_signature_with_reason function (dbus-marshal-validate.c) in D-Bus (aka DBus) before 1.2.14 uses incorrect logic to validate a basic type, which allows remote attackers to spoof a signature via a crafted key. NOTE: this is due to an incorrect fix for CVE-2008-3834.
CVE-2008-0595 4 Fedoraproject, Freedesktop, Mandrakesoft and 1 more 4 Fedora, Dbus, Mandrake Linux and 1 more 2022-02-07 4.6 MEDIUM N/A
dbus-daemon in D-Bus before 1.0.3, and 1.1.x before 1.1.20, recognizes send_interface attributes in allow directives in the security policy only for fully qualified method calls, which allows local users to bypass intended access restrictions via a method call with a NULL interface.
CVE-2020-12049 2 Canonical, Freedesktop 2 Ubuntu Linux, Dbus 2021-03-04 4.9 MEDIUM 5.5 MEDIUM
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.
CVE-2019-12749 2 Canonical, Freedesktop 2 Ubuntu Linux, Dbus 2020-08-24 3.6 LOW 7.1 HIGH
dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent client connection came from an attacker-chosen uid, allowing authentication bypass.
CVE-2008-3834 1 Freedesktop 3 Dbus, Dbus1.0, Dbus1.1.0 2017-09-28 2.1 LOW N/A
The dbus_signature_validate function in the D-bus library (libdbus) before 1.2.4 allows remote attackers to cause a denial of service (application abort) via a message containing a malformed signature, which triggers a failed assertion error.
CVE-2011-2533 1 Freedesktop 1 Dbus 2017-08-28 3.3 LOW N/A
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/.
CVE-2008-4311 1 Freedesktop 1 Dbus 2017-08-07 4.6 MEDIUM N/A
The default configuration of system.conf in D-Bus (aka DBus) before 1.2.6 omits the send_type attribute in certain rules, which allows local users to bypass intended access restrictions by (1) sending messages, related to send_requested_reply; and possibly (2) receiving messages, related to receive_requested_reply.
