題名:
c-ares-1.19.1-1.el9
影響のあるチャネル:
MIRACLE LINUX 9 for x86_64
Severity:
Moderate
Description:
以下項目について対処しました。
[Security Fix]
- Node.js の c-ares パッケージの ares_set_sortlist 関数
には、入力文字列の妥当性を確認しない問題があるため、
リモートの攻撃者により、細工された文字列の入力を
介して、スタックオーバーフローの発生やサービス拒否
攻撃を可能とする脆弱性が存在します。(CVE-2022-4904)
- c-ares には、CARES_RANDOM_FILE ビルドオプション
を設定していないことに起因して rand() 関数が使用されて
しまう問題があるため、リモートの攻撃者により、内部
で利用されている乱数の予測を可能とする脆弱性が存在
します。(CVE-2023-31124)
- c-ares の ares_inet_net_pton() 関数には、バッファ
アンダーフローの問題があるため、ローカルの攻撃者に
より、"0::00:00:00/2" などの特定の IPv6 アドレスの入力
を介して、クラッシュの発生とこれに起因するサービス
拒否攻撃を可能とする脆弱性が存在します。
(CVE-2023-31130)
- c-ares には、/dev/urandom デバイスファイルもしくは
RtlGenRandom() 関数が利用できない場合、rand() 関数を
用いて生成した予測可能な乱数を DNS クエリ ID の生成に
使用してしまう問題があるため、リモートの攻撃者により、
DNS 応答の偽装を可能とする脆弱性が存在します。
(CVE-2023-31147)

CVE:
CVE-2022-4904
A flaw was found in the c-ares package. The ares_set_sortlist is missing checks about the validity of the input string, which allows a possible arbitrary length stack overflow. This issue may cause a denial of service or a limited impact on confidentiality and integrity.

CVE-2023-31124
c-ares is an asynchronous resolver library. When cross-compiling c-ares and using the autotools build system, CARES_RANDOM_FILE will not be set, as seen when cross compiling aarch64 android. This will downgrade to using rand() as a fallback which could allow an attacker to take advantage of the lack of entropy by not using a CSPRNG. This issue was patched in version 1.19.1.

CVE-2023-31130
c-ares is an asynchronous resolver library. ares_inet_net_pton() is vulnerable to a buffer underflow for certain ipv6 addresses, in particular "0::00:00:00/2" was found to cause an issue. C-ares only uses this function internally for configuration purposes which would require an administrator to configure such an address via ares_set_sortlist(). However, users may externally use ares_inet_net_pton() for other purposes and thus be vulnerable to more severe issues. This issue has been fixed in 1.19.1.

CVE-2023-31147
c-ares is an asynchronous resolver library. When /dev/urandom or RtlGenRandom() are unavailable, c-ares uses rand() to generate random numbers used for DNS query ids. This is not a CSPRNG, and it is also not seeded by srand() so will generate predictable output. Input from the random number generator is fed into a non-compilant RC4 implementation and may not be as strong as the original RC4 implementation. No attempt is made to look for modern OS-provided CSPRNGs like arc4random() that is widely available. This issue has been fixed in version 1.19.1.
