Dear Monero users and participants of the Monero ecosystem,
|
|
|
|
Some vulnerabilities have been identified in the implementation of
|
|
Monero multisignature wallets.
|
|
These vulnerabilities do not affect the theory supporting multisigs,
|
|
but affect the current wallet code implementing them.
|
|
|
|
Initially disclosed and discussed via the vulnerability response
|
|
process*, the discussion has been enlarged to other key developers and
|
|
MRL contributors. We agreed together that a public announcement had to
|
|
be made.
|
|
|
|
These vulnerabilities affect (i) multisignature wallet creation and
|
|
(ii) multisignature transaction signing.
|
|
They can lead to funds being stolen by one of the signing parties.
|
|
|
|
Until a fix is released, we strongly recommend not to perform any
|
|
multisignature transaction unless all signing parties can be trusted.
|
|
If all signing parties cannot be trusted, no transaction should be
|
|
attempted. Funds are not at risk if they are not moved and if the
|
|
wallet-creation process was not abused.
|
|
|
|
A fix is currently being reviewed. At this stage we hope to have a
|
|
pull request ready within a week, together with a more detailed
|
|
description of the issues.
|
|
|
|
