unix_random.c in lshd for lsh 2.0.1 leaks file descriptors related to the randomness generator, which allows local users to cause a denial of service by truncating the seed file, which prevents the server from starting, or obtain sensitive seed information that could be used to crack keys.

Unknown vulnerability in lshd in Lysator LSH 1.x and 2.x before 2.0.1 allows remote attackers to cause a denial of service via unknown vectors.
