因此，會受到 ALAS2023-2023-204 公告中所提及的多個弱點影響。

  - 處理檔案時，malloc 會儲存目前行的資料。處理註解時，malloc 未正確存取已釋放的記憶體 (釋放後使用)。(CVE-2021-33641)

  - 處理檔案時，more_curly() 函式的 next_inline() 中會發生無限迴圈。
    (CVE-2021-33642)

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。

因此，它受到 ALAS2023-2023-204 公告中提及的多个漏洞影响。

  - 处理文件时，malloc 会存储当前行的数据。处理注释时，malloc 未正确访问已释放的内存（释放后使用）。(CVE-2021-33641)

  - 处理文件时，more_curly() 函数的 next_inline() 发生无限循环。
    (CVE-2021-33642)

请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。

したがって、ALAS2023-2023-204 のアドバイザリに記載されている複数の脆弱性の影響を受けます。

  - ファイルを処理するとき、malloc は現在の行のデータを保存します。コメントを処理するときに、malloc が解放されたメモリに誤ってアクセスします (メモリ解放後使用)。(CVE-2021-33641)

  - ファイルが処理されるとき、more_curly() 関数の next_inline() で無限ループが発生します。
    (CVE-2021-33642)

Nessus はこれらの問題をテストしておらず、代わりにアプリケーションが自己報告するバージョン番号にのみ依存しています。

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

  - When processing files, malloc stores the data of the current line. When processing comments, malloc     incorrectly accesses the released memory (use after free). (CVE-2021-33641)

  - When a file is processed, an infinite loop occurs in next_inline() of the more_curly() function.
    (CVE-2021-33642)

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 ALAS2023-2023-204 advisory.

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.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2023-000152 advisory.

    ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when     announcing a new security problem. When the candidate has been publicized, the details for this candidate     will be provided.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

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