%description

The following settings are changed:
|
|
|
|
deactivates previews in Dolphin;
|
|
deactivates previews in Nautilus;
|
|
deactivates thumbnails in Thunar;
|
|
deactivates TCP timestamps;
|
|
deactivates Netfilter's connection tracking helper;
|
|
|
|
TCP time stamps (RFC 1323) allow for tracking clock
|
|
information with millisecond resolution. This may or may not allow an
|
|
attacker to learn information about the system clock at such
|
|
a resolution, depending on various issues such as network lag.
|
|
This information is available to anyone who monitors the network
|
|
somewhere between the attacked system and the destination server.
|
|
It may allow an attacker to find out how long a given
|
|
system has been running, and to distinguish several
|
|
systems running behind NAT and using the same IP address. It might
|
|
also allow one to look for clocks that match an expected value to find the
|
|
public IP used by a user.
|
|
|
|
Hence, this package disables this feature by shipping the
|
|
/etc/sysctl.d/tcp_timestamps.conf configuration file.
|
|
|
|
Note that TCP time stamps normally have some usefulness. They are
|
|
needed for:
|
|
|
|
* the TCP protection against wrapped sequence numbers; however, to
|
|
trigger a wrap, one needs to send roughly 2^32 packets in one
|
|
minute: as said in RFC 1700, "The current recommended default
|
|
time to live (TTL) for the Internet Protocol (IP) [45,105] is 64".
|
|
So, this probably won't be a practical problem in the context
|
|
of Anonymity Distributions.
|
|
|
|
* "Round-Trip Time Measurement", which is only useful when the user
|
|
manages to saturate their connection. When using Anonymity Distributions,
|
|
probably the limiting factor for transmission speed is rarely the capacity
|
|
of the user connection.
|
|
|
|
Netfilter's connection tracking helper module increases kernel attack
|
|
surface by enabling superfluous functionality such as IRC parsing in
|
|
the kernel. (!)
|
|
|
|
Hence, this package disables this feature by shipping the
|
|
/etc/sysctl.d/nf_conntrack_helper.conf configuration file.
