Networkmanager: networkmanager: local privilege escalation via malformed mud urls in dhclient backend

A flaw was found in NetworkManager. This local privilege escalation vulnerability exists in NetworkManager's dhclient backend when processing malformed Manufacturer Usage Description (MUD) URLs. A local user can exploit this flaw to escalate privileges by triggering a script via a crafted MUD URL, provided an administrator has explicitly configured NetworkManager to use dhclient. This issue does not affect default configurations of NetworkManager.

Networkmanager: networkmanager file access

A flaw was found in NetworkManager. The NetworkManager package allows access to files that may belong to other users. NetworkManager allows non-root users to configure the system's network. The daemon runs with root privileges and can access files owned by users different from the one who added the connection.

Networkmanager: denial of service

A flaw was found in NetworkManager. When a system running NetworkManager with DEBUG logs enabled and an interface eth1 configured with LLDP enabled, a malicious user could inject a malformed LLDP packet. NetworkManager would crash, leading to a denial of service.
