D-Bus _dbus_validate_signature_with_reason() function (dbus-marshal-validate.c) spoofing
| dbus-dbusmarshalvalidate-spoofing (50385) |  Medium Risk |
Description:
D-Bus is vulnerable to spoofing attacks. The _dbus_validate_signature_with_reason() function (dbus-marshal-validate.c) uses incorrect logic to validate a basic type. A remote attacker could exploit this vulnerability using a specially-crafted key to spoof a signature.
