最近,比特幣開發人員暴露了一個嚴重的軟體缺陷,該缺陷損害了超過 13% 的執行網路策略的節點。發現為 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.
比特幣開發者最近強調了一個嚴重的軟體漏洞,影響了超過 13% 的執行網路策略的節點。此問題編號為 CVE-2024-35202,影響運行比特幣核心版本 25.0 以上的節點。
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.
根據 Protos 的說法,這些節點很容易受到遠端關閉攻擊,這是由於程式對「blocktxn」的處理造成的。利用緊湊塊協定中的衝突,攻擊者可以將易受攻擊的節點置於無效狀態,最終使其崩潰。
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.
該漏洞是由於緊湊塊協議而產生的,該協議利用縮寫的交易 ID 來減少頻寬消耗。雖然該協議提高了效率,但它也為攻擊者提供了引入衝突的途徑。這些衝突可能會促使易受攻擊的節點請求完整的區塊,從而可能導致該過程中的節點崩潰。
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 發現並報告了該漏洞,並提供了修復。該修復已包含在 2023 年 5 月發布的 Bitcoin Core 25.0 版本中。
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.
由於該錯誤的性質,普通駭客不太可能利用它來獲取經濟利益。然而,較大的團體,例如政府或公司,可能會利用它來試圖破壞比特幣網路。
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.
該漏洞是更廣泛趨勢的一部分,工程師發現了舊版比特幣核心版本中的關鍵漏洞。由於比特幣核心軟體不會自動更新,節點營運商必須手動下載並安裝新版本。
Without these updates, nodes running outdated software remain vulnerable to attacks that could shut them down remotely.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.
如果沒有這些更新,運行過時軟體的節點仍然容易受到可能遠端關閉它們的攻擊。目前,大約 13.7% 的比特幣節點仍然存在這種風險。
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.
為了防範這些漏洞,開發人員強烈建議節點業者升級到最新的比特幣核心版本。為了持續努力保護網絡,Bitcoin Core 的創建者始終致力於增強系統的安全性和穩定性。
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.
正如之前報導的那樣,Bitcoin Core 28.0 版本最近發布,以解決 9 月發現的另一個漏洞。此次升級引入了額外的安全措施,而不會影響軟體的功能,最終增強用戶隱私和網路的整體彈性。
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.
截至撰寫本文時,BTC 價格約為 62,804.68 美元,過去 24 小時小幅上漲 0.36%。
