openSUSE-SU-2023:0361-1

This update for tor fixes the following issues:

• tor 0.4.8.8:

  • Mitigate an issue when Tor compiled with OpenSSL can crash during handshake with a remote relay. (TROVE-2023-004, boo#1216873)
  • Regenerate fallback directories generated on November 03, 2023.
  • Update the geoip files to match the IPFire Location Database, as retrieved on 2023/11/03
  • directory authority: Look at the network parameter 'maxunmeasuredbw' with the correct spelling
  • vanguards addon support: Count the conflux linked cell as valid when it is successfully processed. This will quiet a spurious warn in the vanguards addon

• tor 0.4.8.7:

  • Fix an issue that prevented us from pre-building more conflux sets after existing sets had been used

• tor 0.4.8.6:

  • onion service: Fix a reliability issue where services were expiring their introduction points every consensus update. This caused connectivity issues for clients caching the old descriptor and intro points
  • Log the input and output buffer sizes when we detect a potential compression bomb
  • Disable multiple BUG warnings of a missing relay identity key when starting an instance of Tor compiled without relay support
  • When reporting a pseudo-networkstatus as a bridge authority, or answering 'ns/purpose/*' controller requests, include accurate published-on dates from our list of router descriptors
  • Use less frightening language and lower the log-level of our run-time ABI compatibility check message in our Zstd compression subsystem

• tor 0.4.8.5:

  • bugfixes creating log BUG stacktrace

• tor 0.4.8.4:

  • Extend DoS protection to partially opened channels and known relays
  • Dynamic Proof-Of-Work protocol to thwart flooding DoS attacks against hidden services. Disabled by default, enable via 'HiddenServicePoW' in torrc
  • Implement conflux traffic splitting
  • Directory authorities and relays now interact properly with directory authorities if they change addresses

• tor 0.4.7.14:

  • bugfix affecting vanguards (onion service), and minor fixes

• Enable support for scrypt()
