    Summary: Security update for tor

    Details: 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()
