rippled version 0.90.1

Ripple has released rippled version 0.90.1, which 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.

Action Required

If you operate a rippled server, then you should upgrade to rippled version 0.90.1 as soon as possible.

Impact of Not Upgrading

If you operate a rippled server but do not upgrade to version 0.90.1, your server may experience restarts or outages.

Upgrading

For instructions on updating rippled on supported platforms, see here: Updating rippled

The SHA-256 for the rpm is: a22aff93d3de98ac3e1d775612e75e0e81aa7e6c18187db01efed485f854bab0

The SHA-256 for the source rpm is: abaaaba2039c8cd93218fd6a23c79b32bfb6eba92a465b7f9c0716b37fb45795

For other platforms, please compile version 0.90.1 from source. See rippled Builds for instructions by platform. For instructions building rippled from source on Ubuntu Linux, see Build and Run rippled on Ubuntu.

The first log entry should be the change setting the version:

Network Update

The Ripple operations team plans to deploy version 0.90.1 to all rippled servers under its operational control, including private clusters, starting at 5:00 PM PST on Thursday, 2018-03-22. The deployment is expected to complete within 4 hours. The network should continue to operate during deployment and no outage is expected.

Other Information

Acknowledgements

Ripple thanks Guido Vranken for responsibly disclosing a potential out-of-bounds memory access in the base58 encoder/decoder, a vulnerability in the parsing code handling nested serialized objects and a codepath where untrusted public input involving public keys was used without first being properly validated. These issues could be exploited to mount a denial of service attack.

Bug Bounties and Responsible Disclosures

We welcome reviews of the rippled codebase and urge reviewers to responsibly disclose any issues that they may find. For more on Ripple's Bug Bounty program, please visit https://ripple.com/bug-bounty/.

Boost Compatibility

When compiling rippled from source, you must use a compatible version of the Boost library. Ripple recommends Boost 1.64.0 for all platforms.

Other compatible versions differ by platform. Boost 1.58.0 is compatible on Linux but not on Windows. On macOS, Boost 1.58.0 is not compatible with the Clang compiler version 4.0+. On all platforms, Boost 1.66.0 compatibility in rippled 0.90.1 is experimental.

Upcoming Features

The previously announced DepositAuth, Checks and fix1513 amendments are now open for voting on the XRP Ledger. The DepositAuth Amendment lets an account strictly reject any incoming money from transactions sent by other accounts. The Checks Amendment allows users to create a deferred payment that can be cancelled or cashed by its intended recipient. The fix1513 amendment fixes a minor bug in rounding calculations. Ripple expects the DepositAuth, Checks, and fix1513 amendments to be enabled on Thursday, 2018-04-05.

The previously announced FlowCross Amendment will be enabled on a future date (TBA).

Compiling rippled with scons is deprecated. Starting in rippled version 1.0, the only supported build will be using CMake.

An upcoming version of rippled will switch to using the Boost.Beast library instead of the Beast library from the rippled source code. As part of this change, the minimum supported version of Boost will change to be a version incorporating Boost.Beast.

Ripple does not expect to enable the SHAMapV2, Tickets, or OwnerPaysFee amendments before the next release of rippled. These amendments have been disabled in the source code so rippled 0.90.1 will not show them as available. Ripple plans to re-introduce some or all of these amendments in a future version of rippled.
