The Litecoin development team announced the release of Litecoin Core version 0.21.4, which includes critical security updates and functional enhancements. This release aims to strengthen the Litecoin network and address several critical issues.

莱特币开发团队宣布发布莱特币核心版本0.21.4，其中包括关键的安全更新和功能增强。此版本旨在加强莱特币网络并解决几个关键问题。

Among the vulnerabilities fixed is CVE-2024-40202, which could allow remote attackers to carry out a DoS attack by inserting uncommitted transactions into the blocktxn message. This would trigger assertion errors and lead to the node exiting. The patch included in this release verifies that all transactions in the message correspond to the Merkle root of the block, ensuring transaction validity.

已修复的漏洞包括 CVE-2024-40202，该漏洞可能允许远程攻击者通过将未提交的交易插入到 blocktxn 消息中来执行 DoS 攻击。这将触发断言错误并导致节点退出。此版本中包含的补丁验证消息中的所有交易是否对应于块的 Merkle 根，从而确保交易的有效性。

Moreover, the update addresses a problem where a peer could delay the propagation of blocks by sending modified blocks, which could erase the download state of other peers and hinder the propagation process in the network. This improvement, backported from Bitcoin Core (dbfc748), reduces block propagation latency to enhance network throughput.

此外，该更新还解决了一个问题：对等点可能会通过发送修改后的块来延迟块的传播，这可能会擦除其他对等点的下载状态并阻碍网络中的传播过程。这一改进是从 Bitcoin Core (dbfc748) 向后移植的，可减少区块传播延迟，从而提高网络吞吐量。

This version also includes a fix for a vulnerability in the miniupnp dependency, where a local attacker could cause an infinite loop and out-of-memory (oom) errors. The issue addressed in this release minimizes the occurrence of network disruptions due to memory depletion.

此版本还修复了 miniupnp 依赖项中的漏洞，本地攻击者可能会在该漏洞中导致无限循环和内存不足 (oom) 错误。此版本中解决的问题最大限度地减少了由于内存耗尽而导致的网络中断的发生。

Additionally, Litecoin Core v0.21.4 updates the -peerblockfilters and -blockfilterindex options to default to "off" when pruning is enabled. This change, along with other test-related improvements, enhances compatibility and reliability, particularly for pruned nodes.

此外，Litecoin Core v0.21.4 将 -peerblockfilters 和 -blockfilterindex 选项更新为在启用修剪时默认为“关闭”。这一变化以及其他与测试相关的改进增强了兼容性和可靠性，特别是对于修剪的节点。

The Litecoin Core v0.21.4 release was made in collaboration with several authors and contributors, including Bitcoin Core developers David Burkett, Hector Chu, and Loshan. Users can download the new version of Litecoin here and are encouraged to report any bugs via the issue tracker on the Litecoin GitHub page.

This security-focused release coincides with increasing prospects for Litecoin's institutional adoption. Canary Capital recently filed the first application for a Litecoin-based ETF with the U.S. Securities and Exchange Commission (SEC), paving the way for institutional investors to access Litecoin.

此次以安全为重点的发布恰逢莱特币的机构采用前景日益乐观。 Canary Capital 最近向美国证券交易委员会 (SEC) 提交了第一份基于莱特币的 ETF 申请，为机构投资者投资莱特币铺平了道路。

The S-1 filing, made public on Oct. 15, marks a crucial first step, with the firm also needing to submit a 19b-4 form to gain the exchange's approval. The proposed ETF will hold Litecoin and calculate its net asset value daily.

10 月 15 日公开的 S-1 申请标志着关键的第一步，该公司还需要提交 19b-4 表格以获得交易所的批准。拟议的 ETF 将持有莱特币并每日计算其资产净值。

If approved, the spot LTC ETF would open the door for the approval of other cryptocurrency ETFs, with XRP being another candidate once the lawsuit between Ripple and the SEC is resolved.

如果获得批准，现货 LTC ETF 将为其他加密货币 ETF 的批准打开大门，一旦 Ripple 和 SEC 之间的诉讼得到解决，XRP 将成为另一个候选者。

Meanwhile, as these developments unfold, long-term investors continue to show interest in Litecoin. As reported previously by Crypto News Flash, Litecoin recently surpassed Ethereum in the longest average holding period, indicating that the currency continues to capture the attention of HODLers. At the time of writing, LTC is trading at $73.16, up 3.47% in the past day and 4.28% over the past week. It's worth noting that the coin has declined 42% from its all-time high of $412 registered three years ago.

与此同时，随着这些事态的发展，长期投资者继续对莱特币表现出兴趣。正如 Crypto News Flash 之前报道的那样，莱特币最近在最长平均持有期限上超过了以太坊，这表明该货币继续吸引了 HODLers 的关注。截至撰写本文时，LTC 的交易价格为 73.16 美元，过去一天上涨 3.47%，过去一周上涨 4.28%。值得注意的是，该代币的价格较三年前创下的 412 美元历史高点下跌了 42%。
