Descriptions

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.

KDE KAuth, versiones anteriores 5.55, permite el paso de parámetros con tipos arbitrarios a ayudantes que se ejecutan como root sobre DBus a través de DBusHelperProxy.cpp. Ciertos tipos pueden causar caídas y desencadenar la decodificación de imágenes arbitrarias con plugins cargados dinámicamente. En otras palabras, KAuth involuntariamente hace que este código del plugin se ejecute como root, lo que aumenta la severidad de cualquier posible explotación de una vulnerabilidad del plugin.

It was discovered that KAuth incorrectly handled some configuration parameters with specially crafted arbitrary types. An attacker could possibly use this issue to cause a denial of service, or possibly execute arbitrary code.
