最近,比特币开发商暴露了一个严重的软件缺陷,该缺陷损害了超过 13% 的执行网络策略的节点。发现为 CVE-2024-35202
Developers of Bitcoin have recently highlighted a critical software vulnerability that affects over 13% of the nodes enforcing the network policies. Tracked as CVE-2024-35202, the issue affects nodes running Bitcoin Core versions past 25.0.
比特币开发者最近强调了一个严重的软件漏洞,该漏洞影响了超过 13% 的执行网络策略的节点。该问题编号为 CVE-2024-35202,影响运行比特币核心版本 25.0 以上的节点。
According to Protos, these nodes are vulnerable to remote shutdown attacks, stemming from the program's handling of "blocktxn." Exploiting conflicts in the compact block protocol, an attacker could put a vulnerable node into an invalid state, ultimately crashing it.
根据 Protos 的说法,这些节点很容易受到远程关闭攻击,这是由于程序对“blocktxn”的处理造成的。利用紧凑块协议中的冲突,攻击者可以将易受攻击的节点置于无效状态,最终使其崩溃。
The vulnerability arises due to the compact block protocol, which utilizes abbreviated transaction IDs to reduce bandwidth consumption. While this protocol enhances efficiency, it also provides attackers with an avenue to introduce conflicts. These conflicts can prompt vulnerable nodes to request a complete block, potentially crashing the node in the process.
该漏洞是由于紧凑块协议而产生的,该协议利用缩写的交易 ID 来减少带宽消耗。虽然该协议提高了效率,但它也为攻击者提供了引入冲突的途径。这些冲突可能会促使易受攻击的节点请求完整的块,从而可能导致该过程中的节点崩溃。
Niklas Gögge discovered and reported the vulnerability, also providing a fix for it. This fix was included in Bitcoin Core version 25.0, which was released in May 2023. However, many nodes have not been upgraded to this version, leaving them susceptible to attack.
Niklas Gögge 发现并报告了该漏洞,并提供了修复程序。该修复已包含在 2023 年 5 月发布的 Bitcoin Core 25.0 版本中。然而,许多节点尚未升级到该版本,导致它们容易受到攻击。
Due to the nature of the bug, it is unlikely to be exploited by common hackers for financial gain. However, larger parties, such as governments or corporations, may utilize it in attempts to disrupt the Bitcoin network.
由于该错误的性质,普通黑客不太可能利用它来获取经济利益。然而,较大的团体,例如政府或公司,可能会利用它来试图破坏比特币网络。
This vulnerability is part of a broader trend, with engineers identifying critical vulnerabilities in older Bitcoin Core versions. Since the Bitcoin Core software does not update automatically, node operators must manually download and install new versions.
该漏洞是更广泛趋势的一部分,工程师们发现了旧版比特币核心版本中的关键漏洞。由于比特币核心软件不会自动更新,节点运营商必须手动下载并安装新版本。
Without these updates, nodes running outdated software remain vulnerable to attacks that could shut them down remotely. Currently, around 13.7% of Bitcoin nodes still pose this risk.
如果没有这些更新,运行过时软件的节点仍然容易受到可能远程关闭它们的攻击。目前,大约 13.7% 的比特币节点仍然存在这种风险。
To protect against these vulnerabilities, developers strongly advise node operators to upgrade to the latest Bitcoin Core version. In a continuous effort to safeguard the network, the creators of Bitcoin Core are consistently working to enhance the system's security and stability.
为了防范这些漏洞,开发人员强烈建议节点运营商升级到最新的比特币核心版本。在不断努力保护网络的过程中,Bitcoin Core 的创建者始终致力于增强系统的安全性和稳定性。
As reported earlier, Bitcoin Core version 28.0 was recently released to address another vulnerability that was identified in September. This upgrade introduces additional security measures without compromising the software's functionality, ultimately enhancing user privacy and the overall resilience of the network.
正如之前报道的那样,Bitcoin Core 28.0 版本最近发布,以解决 9 月份发现的另一个漏洞。此次升级引入了额外的安全措施,而不会影响软件的功能,最终增强用户隐私和网络的整体弹性。
At the time of writing, the price of BTC is around $62,804.68, indicating a slight increase of 0.36% over the past 24 hours.
截至撰写本文时,BTC 价格约为 62,804.68 美元,过去 24 小时小幅上涨 0.36%。
