CVE-2021-34549

CVE-2021-34549 affects Tor prior to 0.4.6.5. The issue is a hashtable-based CPU denial-of-service attack against relays: an attacker can exploit a naive, unkeyed hash used to look up circuits in a circuitmux to construct circuits with chosen circuit IDs, causing collisions and degraded performanc...

Updated tor package fixes security vulnerabilities

Don't allow relays to spoof RELAYEND or RELAYRESOLVED cell on half-closed streams. Previously, clients failed to validate which hop sent these cells: this would allow a relay on a circuit to end a stream that wasn't actually built with it CVE-2021-34548. hashtable-based CPU denial-of-service atta...
