|Gentoo Linux Security Advisory
Title: Tor: Information disclosure (GLSA 200508-16)
Date: August 25, 2005
A flaw in Tor leads to the disclosure of information and the loss of
anonymity, integrity and confidentiality.
Tor is an implementation of second generation Onion Routing, a
connection-oriented anonymizing communication service.
Vulnerable: < 0.1.0.14
Unaffected: >= 0.1.0.14
Architectures: All supported architectures
The Diffie-Hellman implementation of Tor fails to verify the
cryptographic strength of keys which are used during handshakes.
By setting up a malicious Tor server and enticing users to use
this server as first hop, a remote attacker could read and modify all
traffic of the user.
There is no known workaround at this time.
All Tor users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/tor-0.1.0.14"
