UnknownEPSS 1.33%

Last modified

CVE-2009-1189 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.33% chance of exploitation in the next 30 days.
