ZCash Bug: team releases software fix

A ZCash bug has been discovered a few days ago and now the development team has released a new software update to fix this denial of service (DoS) vulnerability.

In fact, in a new blog post, Zooko Wilcox and Paige Peterson – both developers at ZCash – explained how the bug could allow an hacker to crash a zcash node remotely by sending a specific kind of transaction.

ZCash bug found on Wednesday

The bug was found in an update included in the ZCash’s 1.0.4 release, related to how transactions are given priority in a node’s mempool.

This vulnerability was discovered back on Wednesday (April 12nd, 2017).

The blog explains:

“ZcashCo, and several exchanges, wallet vendors, and miners have already deployed a mitigation as well as detectors for this attack vector. No attacks have been detected.”

Zcash published a software update to address this bug, asking users to upgrade their platforms in order to delete the denial of service risk.

The Zcash team  also commented that, should signs emerge that an attack attempt is being made, it would issue alerts and coordinate with related services on a response.

If you don’t know what I’m talking about, Zcash is a digital currency with the special feature of total anonymity thanks to its zero knowledge proof of work called zk-snarks.
