rippled Version 0.90.1

The rippled 0.90.1 release includes fixes for issues reported by external security researchers. These issues, when exploited, could cause a rippled instance to restart or, in some circumstances, stop executing. While these issues can result in a denial of service attack, none affect the integrity of the XRP Ledger and no user funds, including XRP, are at risk.

New and Updated Features

This release has no new features.

Bug Fixes

• Address issues identified by external review:
  • Verify serialized public keys more strictly before using them
    (RIPD-1617, RIPD-1619, RIPD-1621)
  • Eliminate a potential out-of-bounds memory access in the base58
    encoding/decoding logic (RIPD-1618)
  • Avoid invoking undefined behavior in memcpy (RIPD-1616)
  • Limit STVar recursion during deserialization (RIPD-1603)
• Use lock when creating a peer shard rangeset

rippled Version 0.90.0

New and Updated Features

This release has no new features.

Bug Fixes

The rippled 0.80.0 release introduces several enhancements that improve the reliability, scalability and security of the XRP Ledger.

• Changes to the UNL and quorum rules
  • Use a fixed size UNL if the total listed validators are below threshold
  • Ensure a quorum of 0 cannot be configured
  • Set a quorum to provide Byzantine fault tolerance until a threshold of total validators is exceeded, at which time the quorum is 80%
