A vulnerability found on the Linux Kernel that permits local unprivileged users to run arbitrary code with administrative privileges. Latest security upgrades should be applied in order to secure systems against possibly attacks.
Network traffic encrypted using an RSA-based SSL certificate may be decrypted if enough SSLv2 handshake data can be collected. Exploitation of this vulnerability—referred to as DROWN in public reporting—may allow a remote attacker to obtain the private key of a server supporting SSLv2.
A server listens for TCP connections on TCP port 17. Once a connection is established a short message is sent out the connection (and any data received is thrown away). The service closes the connection after sending the quote.
Another quote of the day service is defined as a datagram based application on UDP. A server listens for UDP datagrams on UDP port 17. When a datagram is received, an answering datagram is sent containing a quote (the data in the received datagram is ignored).
