The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-201201-12
(Tor: Multiple vulnerabilities)
Multiple vulnerabilities have been discovered in Tor:
When configured as client or bridge, Tor uses the same TLS
certificate chain for all outgoing connections (CVE-2011-2768).
When configured as a bridge, Tor relays can distinguish incoming
bridge connections from client connections (CVE-2011-2769).
An error in or/buffers.c could result in a heap-based buffer overflow
A remote attacker could possibly execute arbitrary code or cause a
Denial of Service. Furthermore, a remote relay the user is directly
connected to may be able to disclose anonymous information about that
user or enumerate bridges in the user's connection.
There is no known workaround at this time.
