[Security Fix]
- Squid には、制限なく再帰処理が実行され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 X-Forwarded-For
ヘッダーの送信を介して、サービス拒否攻撃を可能とする脆弱性
が存在します。(CVE-2023-50269)
- Squid の HTTP チャンクデコーダーには、再帰処理の不備に
起因した無限ループの発生に至る問題があるため、リモートの
攻撃者により、巧妙に細工された HTTP メッセージの送信を
介して、サービス拒否攻撃を可能とする脆弱性が存在します。
(CVE-2024-25111)
- Squid の HTTP ヘッダーの解析処理には、
request_header_max_size パラメーター、および
reply_header_max_size パラメーターがデフォルト値の場合に
おけるメモリ破壊の問題があるため、リモートの攻撃者により、
非常に大きなヘッダーを持つように細工された HTTP メッセージ
の送信を介して、サービス拒否攻撃を可能とする脆弱性が存在
します。(CVE-2024-25617)

CVE:
CVE-2023-50269
Squid is a caching proxy for the Web. Due to an Uncontrolled Recursion bug in versions 2.6 through 2.7.STABLE9, versions 3.1 through 5.9, and versions 6.0.1 through 6.5, Squid may be vulnerable to a Denial of Service attack against HTTP Request parsing. This problem allows a remote client to perform Denial of Service attack by sending a large X-Forwarded-For header when the follow_x_forwarded_for feature is configured. This bug is fixed by Squid version 6.6. In addition, patches addressing this problem for the stable releases can be found in Squid's patch archives.

CVE-2024-25111
Squid is a web proxy cache. Starting in version 3.5.27 and prior to version 6.8, Squid may be vulnerable to a Denial of Service attack against HTTP Chunked decoder due to an uncontrolled recursion bug. This problem allows a remote attacker to cause Denial of Service when sending a crafted, chunked, encoded HTTP Message. This bug is fixed in Squid version 6.8. In addition, patches addressing this problem for the stable releases can be found in Squid's patch archives. There is no workaround for this issue.

CVE-2024-25617
Squid is an open source caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. Due to a Collapse of Data into Unsafe Value bug ,Squid may be vulnerable to a Denial of Service attack against HTTP header parsing. This problem allows a remote client or a remote server to perform Denial of Service when sending oversized headers in HTTP messages. In versions of Squid prior to 6.5 this can be achieved if the request_header_max_size or reply_header_max_size settings are unchanged from the default. In Squid version 6.5 and later, the default setting of these parameters is safe. Squid will emit a critical warning in cache.log if the administrator is setting these parameters to unsafe values. Squid will not at this time prevent these settings from being changed to unsafe values. Users are advised to upgrade to version 6.5. There are no known workarounds for this vulnerability. This issue is also tracked as SQUID-2024:2
