What is CVE-2006-6893?
CVE-2006-6893 is a medium-severity vulnerability in Tor Tor, published on 8 Jan 2007. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Tor allows remote attackers to discover the IP address of a hidden service by accessing this service at a high rate, thereby changing the server's CPU temperature and consequently changing the pattern of time values visible through (1) ICMP timestamps, (2) TCP sequence numbers, and (3) TCP timestamps, a different vulnerability than CVE-2006-0414. NOTE: it could be argued that this is a laws-of-physics vulnerability that is a fundamental design limitation of certain hardware implementations, so perhaps this issue should not be included in CVE.
Which versions are affected by CVE-2006-6893?
It affects 1 product.
Products include Tor Tor.
How do I fix CVE-2006-6893?
