MGASA-2020-0442 - Updated tor package fixes security vulnerabilities

Publication date: 03 Dec 2020
Type: security
Affected Mageia releases: 7

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).

Channels using obsolete versions of the Tor link protocol are no longer allowed
to circumvent address-canonicity checks. This is only a minor issue, since
such channels have no way to set ed25519 keys, and therefore should always be
rejected for circuits that specify ed25519 identities (tor#40081).

The tor package has been updated to version, fixing these issues and
several other bugs.  See the upstream ChangeLog for details.
