Description David Walser 2021-01-11 23:38:27 CET
An advisory has been issued today (January 11):

The issue is fixed upstream in 4.5.2.

We should probably consider dropping this, as it's highly specialized stuff and has no maintainer.

Mageia 7 is also affected.

Comment 3 David Walser 2021-01-12 18:39:48 CET

Updated coturn package fixes security vulnerability:

When sending a CONNECT request with the XOR-PEER-ADDRESS value of, a
malicious user would be able to relay packets to the loopback interface.
Additionally, when coturn is listening on IPv6, which is default, the loopback
interface can also be reached by making use of either [::1] or [::] as the peer
address (CVE-2020-26262).

If updating is not possible, the setting --denied-peer-ip= can mitigate
this issue.

The coturn package has been patched to fix this issue.


Updated packages in core/updates_testing:

from coturn-4.5.2-1.4.mga7.src.rpm
