rippled team has released
rippled version 0.60.2, which further strengthens handling of cases associated with a previously patched exploit, in which
NoRipple flags were being bypassed by using offers. Ripple requires upgrading to
rippled version 0.60.2 immediately. There are no new features in the 0.60.2 release.
Note: This does not affect XRP transactions.
Ripple will be following up with a postmortem, explaining the previosuly patched exploit, the timeline of events and the actions taken in more detail at a later date.
If you operate a rippled server, then you must upgrade to 0.60.2 immediately.
If you are an individual user, then you should have the
NoRipple flag enabled by default and set the trust line limit to zero on gateways that you do not trust.
If you are an individual user, and you do not have the
NoRipple flag enabled, and you discover a negative balance owed to an unknown account, then you should freeze that individual trust line.
Impact of Not Upgrading
If you operate a rippled server, but do not upgrade to
rippled version 0.60.2, then your server may lose sync with Ripple operated validators more frequently.
If you operate a rippled validating server, but do not upgrade to
rippled version 0.60.2, which prevents
NoRipple flags from being bypassed by using offers, then your server will validate some transactions in a payment path that bypass the blocking effect of the
NoRipple flag using offers.
