Litech Router Advertisement Daemon any version

Buffer overflow in the process_ra function in the router advertisement daemon (radvd) before 1.8.2 allows remote attackers to execute arbitrary code or cause a denial of service (crash) via a negative value in a label_len value.

The process_ra function in the router advertisement daemon (radvd) before 1.8.2 allows remote attackers to cause a denial of service (stack-based buffer over-read and crash) via unspecified vectors.

Directory traversal vulnerability in device-linux.c in the router advertisement daemon (radvd) before 1.8.2 allows local users to overwrite arbitrary files, and remote attackers to overwrite certain files, via a .. (dot dot) in an interface name. NOTE: this can be leveraged with a symlink to overwrite arbitrary files.

The process_rs function in the router advertisement daemon (radvd) before 1.8.2, when UnicastOnly is enabled, allows remote attackers to cause a denial of service (temporary service hang) via a large number of ND_ROUTER_SOLICIT requests.

The router advertisement daemon (radvd) before 1.8.2 does not properly handle errors in the privsep_init function, which causes the radvd daemon to run as root and has an unspecified impact.
