New Flaws in Network Time Protocol

[silicon_toad2000]

Researchers at Boston University have discovered vulnerabilities in the
Network Time Protocol (NTP) could potentially be exploited to cause
serious outages and snoop on encrypted traffic. NTP is used to make sure
that computers' internal clocks are accurate. The connections between
computers and NTP servers are usually not encrypted, which means the
connection could be hijacked to reset clocks.
