CVE-2019-7443
KDE KAuth before 5.55 allows the passing of parameters with arbitrary types to helpers running as root over DBus via DBusHelperProxy.cpp.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.35%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
KDE KAuth before 5.55 allows the passing of parameters with arbitrary types to helpers running as root over DBus via DBusHelperProxy.cpp. Certain types can cause crashes, and trigger the decoding of arbitrary images with dynamically loaded plugins. In other words, KAuth unintentionally causes this plugin code to run as root, which increases the severity of any possible exploitation of a plugin vulnerability.
