Descriptions

Kea configuration and API directives can be used to overwrite arbitrary files, subject to permissions granted to Kea. Many common configurations run Kea as root, leave the API entry points unsecured by default, and/or place the control sockets in insecure paths.
This issue affects Kea versions 2.4.0 through 2.4.1, 2.6.0 through 2.6.2, and 2.7.0 through 2.7.8.

A vulnerability was found in the Kea package. If an attacker has access to a local user account and the Kea API entry points are not secured, the attacker may use the API to modify Kea's configuration files or overwrite any system's file which a Kea running user has write access. This may be leveraged to cause system-wide denial of service or to achieve a local privilege escalation. Additionally, if Kea's control sockets are enabled and placed in an insecure location, any local user may impersonate the Kea service and prevent the real Kea service from starting.

Kea configuration and API directives can be used to overwrite arbitrary files, subject to permissions granted to Kea. Many common configurations run Kea as root, leave the API entry points unsecured by default, and/or place the control sockets in insecure paths. This issue affects Kea versions 2.4.0 through 2.4.1, 2.6.0 through 2.6.2, and 2.7.0 through 2.7.8.

These are all security issues fixed in the kea-2.6.3-1.1 package on the GA media of openSUSE Tumbleweed.
