tor source package in Ubuntu


tor ( unstable; urgency=high

  * New upstream version, including among others:
    - Fix a denial of service bug where an attacker could use a
      malformed directory object to cause a Tor instance to pause while
      OpenSSL would try to read a passphrase from the terminal. (Tor
      instances run without a terminal, which is the case for most Tor
      packages, are not impacted.) Fixes bug 24246; bugfix on every
      version of Tor. Also tracked as TROVE-2017-011 and CVE-2017-8821.
      Found by OSS-Fuzz as testcase 6360145429790720.
    - Fix a denial of service issue where an attacker could crash a
      directory authority using a malformed router descriptor. Fixes bug
      24245; bugfix on Also tracked as TROVE-2017-010
      and CVE-2017-8820.
    - When checking for replays in the INTRODUCE1 cell data for a
      (legacy) onion service, correctly detect replays in the RSA-
      encrypted part of the cell. We were previously checking for
      replays on the entire cell, but those can be circumvented due to
      the malleability of Tor's legacy hybrid encryption. This fix helps
      prevent a traffic confirmation attack. Fixes bug 24244; bugfix on This issue is also tracked as TROVE-2017-009
      and CVE-2017-8819.
    - Fix a use-after-free error that could crash v2 Tor onion services
      when they failed to open circuits while expiring introduction
      points. Fixes bug 24313; bugfix on This issue is
      also tracked as TROVE-2017-013 and CVE-2017-8823.
    - When running as a relay, make sure that we never build a path
      through ourselves, even in the case where we have somehow lost the
      version of our descriptor appearing in the consensus. Fixes part
      of bug 21534; bugfix on This issue is also tracked
      as TROVE-2017-012 and CVE-2017-8822.
    - When running as a relay, make sure that we never choose ourselves
      as a guard. Fixes part of bug 21534; bugfix on This
      issue is also tracked as TROVE-2017-012 and CVE-2017-8822.
  * Build-depend on libcap-dev on linux-any so we can build tor with
    capabilities support to retain the capability to bind to low ports;
    closes: #882281, #700179.

tor: anonymizing overlay network for TCP

 Tor is a connection-based low-latency anonymous communication system.
 Clients choose a source-routed path through a set of relays, and
 negotiate a "virtual circuit" through the network, in which each relay
 knows its predecessor and successor, but no others. Traffic flowing
 down the circuit is decrypted at each relay, which reveals the
 downstream relay.
 Basically, Tor provides a distributed network of relays. Users bounce
 their TCP streams (web traffic, ftp, ssh, etc) around the relays, and
 recipients, observers, and even the relays themselves have difficulty
 learning which users connected to which destinations.
 This package enables only a Tor client by default, but it can also be
 configured as a relay and/or a hidden service easily.
 Client applications can use the Tor network by connecting to the local
 socks proxy interface provided by your Tor instance. If the application
 itself does not come with socks support, you can use a socks client
 such as torsocks.
 Note that Tor does no protocol cleaning on application traffic. There
 is a danger that application protocols and associated programs can be
 induced to reveal information about the user. Tor depends on Torbutton
 and similar protocol cleaners to solve this problem. For best
 protection when web surfing, the Tor Project recommends that you use
 the Tor Browser Bundle, a standalone tarball that includes static
 builds of Tor, Torbutton, and a modified Firefox that is patched to fix
 a variety of privacy bugs.

tor-dbgsym: debug symbols for tor
tor-geoipdb: GeoIP database for Tor

 This package provides a GeoIP database for Tor, i.e. it maps IPv4 addresses
 to countries.
 Bridge relays (special Tor relays that aren't listed in the main Tor
 directory) use this information to report which countries they see
 connections from. These statistics enable the Tor network operators to
 learn when certain countries start blocking access to bridges.
 Clients can also use this to learn what country each relay is in, so
 Tor controllers like arm or Vidalia can use it, or if they want to
 configure path selection preferences.
