Bitcoin Core Integrates 2 New Security Advisories

As a seasoned analyst with over two decades of experience in the financial industry, I have witnessed the evolution of digital currencies from a mere concept to a global phenomenon. The recent security measures implemented by Bitcoin Core, such as addressing vulnerabilities like remote crashes due to addr message spam and malicious UPnP devices on local networks, are commendable steps towards ensuring the stability and trustworthiness of this decentralized system.


To enhance the safety of cryptocurrency platforms, Bitcoin Core has chosen to incorporate two recently issued security recommendations. These advice documents detail some previous security issues Bitcoin Core faced and their solutions, aiming to assist other developers in avoiding similar security threats.

Bitcoin Core Outlined Vulnerabilities and Fixes

Experiencing security threats such as data breaches or taking advantage of weaknesses often results in the theft of digital currencies (cryptocurrencies). Nevertheless, companies dealing with cryptocurrencies are actively searching for methods and solutions aimed at safeguarding their systems and clients.

As a crypto investor, I’ve encountered instances where system crashes can occur due to excessive addr message spamming. These messages, intended to overload and crash the system, might originate from spammed nodes. Fortunately, a solution for this issue was addressed in Bitcoin Core v22.0 on September 14, 2021.

On June 3, 2020, version 0.20.0 of Bitcoin Core implemented three solutions addressing two separate vulnerabilities. One solution addressed an issue in the BIP70 implementation within Bitcoin-Qt, where opening a BIP72 URI could cause the software to silently crash without warning. The second solution was necessary for preventing a malformed GETDATA message from causing 100% CPU usage on the receiving node.

In many cases, systems handle the issue of assigning up to 50 MB of memory per malicious INV message sender, especially when that person is acting as an attacker. These issues are often classified according to their level of threat, ranging from Low to Critical severity.

Bitcoin and the Growing Adoption

Significantly, Bitcoin Core issued security notices as the Bitcoin world experiences growing interest. Swiftly, Spot Bitcoin ETFs have seen remarkable advancements. Despite Grayscale’s outflows, influxes continue to pour in. In a recent trading day, the Grayscale GBTC fell by over 11%.

Alternatively, some market analysts believe the move could be due to the upcoming transition of a part of GBTC’s Bitcoin holdings to the recently created Mini Trust.

In recent weeks, the Donald Trump presidential campaign has garnered increased interest in Bitcoin. This surge began when he announced his acceptance of cryptocurrency donations. Notable figures within the crypto industry have since contributed to Trump’s campaign. An impressive $25 million was raised by Trump during a Bitcoin Conference in Nashville.
