Mageia 7: MGASA-2020-0442 Moderate: Tor Channel Security Fix

mageia
Calendar Grey December 3, 2020
Dist Mageia Esm H88
The newly released tor package addresses significant vulnerabilities within Mageia's core system, introducing improved channel authentication.
When completing a channel, relays now check more thoroughly to make sure that it matches any pending circuits before attaching those circuits

Summary

When completing a channel, relays now check more thoroughly to make sure that it matches any pending circuits before attaching those circuits. Previously, address correctness and Ed25519 identities were not checked in this case, but only when extending circuits on an existing channel (TROVE-2020-005).
