Description:
以下項目について対処しました。
[Security Fix]
- Node.js の fetch() 関数には、リモートの攻撃者により、
細工された URL を介して、サービス拒否攻撃 (メモリ枯渇)
を可能とする脆弱性が存在します。(CVE-2024-22025)
- c-ares の ares__read_line() 関数には、バッファー領域
の範囲外読み取りの問題があるため、ローカルの攻撃者に
より、/etc/resolv.conf、/etc/nsswitch.conf、HOSTALIASES、
/etc/hosts ファイルなどの解析対象のファイルの行の冒頭に
NULL 文字が埋め込まれるように細工されたファイルの処理
を介して、サービス拒否攻撃 (クラッシュの発生) を可能と
する脆弱性が存在します。(CVE-2024-25629)
- Node.js の HTTP サーバー機能には、Content Length ヘッダー
の前に空白文字が含まれている場合の解析処理に問題がある
ため、リモートの攻撃者により、細工された HTTP リクエスト
を介して、HTTP リクエストスマグリング攻撃、およびクロス
サイトスクリプティング攻撃を可能とする脆弱性が存在します。
(CVE-2024-27982)
- Node.js の HTTP/2 プロトコルの実装には、単一ストリーム
内で送信可能な CONTINUATION フレームのサイズが制限されて
いない問題があるため、リモートの攻撃者により、細工された
HTTP/2 CONTINUATION フレームを含むパケットの送信を
介して、サービス拒否攻撃 (メモリ枯渇) を可能とする脆弱性
が存在します。(CVE-2024-27983)
- nghttp2 の HTTP/2 プロトコルスタックには、HPACK
コンテキストのストリームのリセット後も
HTTP/2 CONTINUATION フレームを読み取り続けてしまう問題
があるため、リモートの攻撃者により、細工されたパケットの
送信を介して、サービス拒否攻撃 (CPU リソースおよびメモリ
の枯渇) を可能とする脆弱性が存在します。(CVE-2024-28182)

CVE:
CVE-2024-22025
A vulnerability in Node.js has been identified, allowing for a Denial of Service (DoS) attack through resource exhaustion when using the fetch() function to retrieve content from an untrusted URL. The vulnerability stems from the fact that the fetch() function in Node.js always decodes Brotli, making it possible for an attacker to cause resource exhaustion when fetching content from an untrusted URL. An attacker controlling the URL passed into fetch() can exploit this vulnerability to exhaust memory, potentially leading to process termination, depending on the system configuration.

CVE-2024-25629
c-ares is a C library for asynchronous DNS requests. `ares__read_line()` is used to parse local configuration files such as `/etc/resolv.conf`, `/etc/nsswitch.conf`, the `HOSTALIASES` file, and if using a c-ares version prior to 1.27.0, the `/etc/hosts` file. If any of these configuration files has an embedded `NULL` character as the first character in a new line, it can lead to attempting to read memory prior to the start of the given buffer which may result in a crash. This issue is fixed in c-ares 1.27.0. No known workarounds exist.

CVE-2024-27982
The team has identified a critical vulnerability in the http server of the most recent version of Node, where malformed headers can lead to HTTP request smuggling. Specifically, if a space is placed before a content-length header, it is not interpreted correctly, enabling attackers to smuggle in a second request within the body of the first.

CVE-2024-27983
An attacker can make the Node.js HTTP/2 server completely unavailable by sending a small amount of HTTP/2 frames packets with a few HTTP/2 frames inside. It is possible to leave some data in nghttp2 memory after reset when headers with HTTP/2 CONTINUATION frame are sent to the server and then a TCP connection is abruptly closed by the client triggering the Http2Session destructor while header frames are still being processed (and stored in memory) causing a race condition.

CVE-2024-28182
nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. The nghttp2 library prior to version 1.61.0 keeps reading the unbounded number of HTTP/2 CONTINUATION frames even after a stream is reset to keep HPACK context in sync. This causes excessive CPU usage to decode HPACK stream. nghttp2 v1.61.0 mitigates this vulnerability by limiting the number of CONTINUATION frames it accepts per stream. There is no workaround for this vulnerability.
