CVE-2006-6893

The CVE-2006-6893 entry concerns Tor, specifically a timing/side-channel vulnerability where remote attackers can deduce a hidden service's IP by querying the service at high rates. The observed effect is interference with time-value patterns (ICMP timestamps, TCP sequence numbers, TCP timestamps...

CVE-2006-6893

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, ...

ipsec -- reply attack vulnerability

Problem Description IPsec provides an anti-replay service which when enabled prevents an attacker from successfully executing a replay attack. This is done through the verification of sequence numbers. A programming error in the fastipsec4 implementation results in the sequence number associated...

kernel -- TCP connection stall denial of service

Problem Description Two problems have been discovered in the FreeBSD TCP stack. First, when a TCP packets containing a timestamp is received, inadequate checking of sequence numbers is performed, allowing an attacker to artificially increase the internal "recent" timestamp for a connection. Secon...

CVE-2005-0356

Multiple TCP implementations with Protection Against Wrapped Sequence Numbers PAWS with the timestamps option enabled allow remote attackers to cause a denial of service connection loss via a spoofed packet with a large timer value, which causes the host to discard later packets because they appe...
