因此，它受到 ALAS2023-2023-016 公告中所提及的多個弱點影響。

  - Apache Portable Runtime 1.6.3 版本中修正了 apr_time_exp*() 函式中的超出邊界陣列讀取弱點 (CVE-2017-12613)。對於此問題的修復程序未移轉到 APR 1.7.x 分支，因此 1.7.0 版相比 1.6.3 版有所退步，容易受到同一問題影響。(CVE-2021-35940)

  - Apache Portable Runtime (APR) 的 apr_encode 函式中有整數溢位或換行弱點，允許攻擊者超出緩衝區邊界進行寫入。此問題會影響 Apache Portable Runtime (APR) 1.7.0 版。(CVE-2022-24963)

請注意，Nessus 並未測試這些問題，而是僅依據應用程式自我報告的版本號碼作出判斷。

遠端 Redhat Enterprise Linux 7/8 主機上安裝的套件受到 RHSA-2023: 4629 公告中所提及的多個弱點影響。

  - Apache Portable Runtime (APR) 的 apr_encode 函式中有整數溢位或換行弱點，允許攻擊者超出緩衝區邊界進行寫入。此問題會影響 Apache Portable Runtime (APR) 1.7.0 版。(CVE-2022-24963)

  - Apache HTTP Server 的 mod_proxy_ajp 中存在對 HTTP 要求解釋不一致 (「HTTP 要求走私」) 弱點，攻擊者可藉此將要求走私到其轉送要求的 AJP 伺服器。此問題會影響 Apache HTTP Server 2.4、2.4.54 以及更舊版本。
    (CVE-2022-36760)

  - 在 Apache HTTP Server 2.4.55 之前的版本中，惡意後端可造成回應標頭提早截斷，進而導致某些標頭被合併到回應內文中。如果較新版本中的標頭具有任何安全性目的，則用戶端將不會對其進行解譯。(CVE-2022-37436)

  - 在 ModSecurity 2.9.6 之前版本和 3.0.8 之前的 3.x 版中，HTTP multipart 要求的剖析不正確 ，且可繞過 Web 應用程式防火牆。注意：這與 CVE-2022-39956 相關，但可被視為對 ModSecurity (C 語言) 程式碼基底的獨立變更。(CVE-2022-48279)

  - 2.9.7 版之前的 ModSecurity 中存在檔案上傳中的「\0 」位元組處理錯誤問題，在執行讀取 FILES_TMP_CONTENT 集合的規則時，此問題可造成 Web 應用程式防火牆繞過以及 Web 應用程式發生緩衝區溢位。(CVE-2023-24021)

  - Apache HTTP Server 中透過 mod_proxy_uwsgi 造成的 HTTP 回應走私弱點。此問題會影響 Apache HTTP Server：從 2.4.30 到 2.4.55。原始回應標頭中的特殊字元可截斷/分割轉送至用戶端的回應。(CVE-2023-27522)

  - 在低於 v8.1.0 的 curl 中存在釋放後使用弱點，體現在 libcurl 使用 SHA 256 雜湊驗證 SSH 伺服器公開金鑰中。此檢查失敗時，libcurl 會在傳回包含 (現已釋放) 雜湊的錯誤訊息之前，釋放記憶體以供指紋識別功能使用。此瑕疵有將敏感堆積型資料插入錯誤訊息中的風險，該訊息可能會顯示給使用者，或可能會遭到洩漏和洩漏。(CVE-2023-28319)

  - curl v8.1.0 之前版本中存在憑證驗證不當弱點，它支援比對 TLS 伺服器憑證中做為主體別名列出的萬用字元符號。curl 可以被構建為針對 TLS 使用自己的名稱比對函式，而不是 TLS 庫提供的函式。此私人萬用字元比對函式會錯誤比對 IDN (國際網域名稱) 主機，並因此接受本應不相符的符號。IDN 主機名稱會先轉換為 puny 程式碼，然後再用於憑證檢查。Puny 編碼名稱一律以「xn--」開頭，且不應允許進行符號比對，但 curl 中的萬用字元檢查仍可檢查「x*」，即使 IDN 名稱很可能不包含任何與「x」類似的符號，仍會被視為與「x*」一致。(CVE-2023-28321)

  - curl v8.1.0 之前版本在進行 HTTP(S) 傳輸時，如果之前曾使用相同的控點發出使用讀取回呼 (「CURLOPT_READFUNCTION」) 的「PUT」要求，則 libcurl 可能會錯誤地使用此回呼來要求要傳送的資料，即使已經設定「CURLOPT_POSTFIELDS」選項亦如此。此缺陷可能會使應用程式意外產生錯誤行為，並在第二次傳輸中傳送錯誤資料或使用釋放後的記憶體，或發生類似情況。從 PUT 變更為 POST 時 (預期如此)，重複使用的控點邏輯中存在此問題。(CVE-2023-28322)

According to the versions of the apr package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Integer Overflow or Wraparound vulnerability in apr_encode functions of Apache Portable Runtime (APR)     allows an attacker to write beyond bounds of a buffer. This issue affects Apache Portable Runtime (APR)     version 1.7.0. (CVE-2022-24963)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-016 advisory.

    An out-of-bounds array read in the apr_time_exp*() functions was fixed in the Apache Portable Runtime     1.6.3 release (CVE-2017-12613). The fix for this issue was not carried forward to the APR 1.7.x branch,     and hence version 1.7.0 regressed compared to 1.6.3 and is vulnerable to the same issue. (CVE-2021-35940)

    Integer Overflow or Wraparound vulnerability in apr_base64 functions of Apache Portable Runtime Utility     (APR-util) allows an attacker to write beyond bounds of a buffer. This issue affects Apache Portable     Runtime Utility (APR-util) 1.6.1 and prior versions. (CVE-2022-24963)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
