Security update for tor
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()
