[Security Fix]
- 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)

CVE:
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.
