There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - PJSIP is a free and open source multimedia communication library written in C with high level API in C,
    C++, Java, C#, and Python languages. SRTP is a higher level media transport which is stacked upon a lower
    level media transport such as UDP and ICE. Currently a higher level transport is not synchronized with its
    lower level transport that may introduce use-after-free issue. This vulnerability affects applications
    that have SRTP capability (`PJMEDIA_HAS_SRTP` is set) and use underlying media transport other than UDP.
    This vulnerability’s impact may range from unexpected application termination to control flow
    hijack/memory corruption. The patch is available as a commit in the master branch. (CVE-2023-38703)

Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - PJSIP 是一個免費的開源多媒體通信庫，用 C 編寫，具有 C、C++、Java、C# 和 Python 語言的高級 API。SRTP 是較高層級的媒體傳輸，可堆疊在較低層級的媒體傳輸 (如 UDP 和 ICE) 上。目前，較高層級的傳輸未與其較低層級的傳輸同步，這可能會造成釋放後使用問題。此弱點會影響具有 SRTP 功能 （已設定 'PJMEDIA_HAS_SRTP'） 並使用 UDP 以外的基礎媒體傳輸的應用程式。
    此弱點的影響範圍可能從應用程式意外終止到控制流程劫持/記憶體損毀。修補程式可在 master 分支中以提交的形式使用。（CVE-2023-38703）

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - PJSIP 是一个免费的开源多媒体通信库，以 C 语言编写，具有 C、C++、Java、C# 和 Python 语言的高级 API。SRTP 是堆栈在较低级别媒体传输（例如 UDP 和 ICE）之上的更高级别媒体传输。目前，较高级别传输未与其较低级别传输同步，这可能引入释放后使用问题。此漏洞会影响具有 SRTP 功能（已设置 `PJMEDIA_HAS_SRTP`）并使用底层媒体传输而非 UDP 的应用程序。
    此漏洞的影响范围可能从应用程序意外终止到控制流劫持/内存损坏等。此修补程序可作为认可在 master 分支中使用。（CVE-2023-38703）

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  - PJSIP は、C、C++、Java、C#、および Python 言語の高レベルの API を備えた C で書かれた、無料のオープンソース マルチメディア通信ライブラリです。SRTP は、UDP や ICE などの低レベルのメディア転送にスタックされる高レベルのメディア転送です。現在、高いレベルのトランスポートは、その低いレベルのトランスポートと同期されないため、use-after-free の問題が生じる可能性があります。この脆弱性の影響を受けるのは、SRTP 機能があり (「PJMEDIA_HAS_SRTP」が設定されており)、UDP 以外の基本的なメディア転送を使用するアプリケーションです。
    この脆弱性の影響は、予期しないアプリケーションの終了から制御フローのハイジャック/メモリ破損まで多岐にわたります。パッチは、マスターブランチでコミットとして利用できます。(CVE-2023-38703)

Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

    Multiple security vulnerabilities have been discovered in Asterisk, an Open     Source Private Branch Exchange.

    CVE-2023-37457

        The 'update' functionality of the PJSIP_HEADER dialplan function can exceed         the available buffer space for storing the new value of a header. By doing         so this can overwrite memory or cause a crash. This is not externally         exploitable, unless dialplan is explicitly written to update a header based         on data from an outside source. If the 'update' functionality is not used         the vulnerability does not occur.

    CVE-2023-38703

        PJSIP is a free and open source multimedia communication library written in         C with high level API in C, C++, Java, C#, and Python languages. SRTP is a         higher level media transport which is stacked upon a lower level media         transport such as UDP and ICE. Currently a higher level transport is not         synchronized with its lower level transport that may introduce a         use-after-free issue. This vulnerability affects applications that have         SRTP capability (`PJMEDIA_HAS_SRTP` is set) and use underlying media         transport other than UDP. This vulnerabilitys impact may range from         unexpected application termination to control flow hijack/memory         corruption.

    CVE-2023-49294

        It is possible to read any arbitrary file even when the `live_dangerously`         option is not enabled.

    CVE-2023-49786

       Asterisk is susceptible to a DoS due to a race condition in the hello        handshake phase of the DTLS protocol when handling DTLS-SRTP for media        setup. This attack can be done continuously, thus denying new DTLS-SRTP        encrypted calls during the attack. Abuse of this vulnerability may lead to        a massive Denial of Service on vulnerable Asterisk servers for calls that        rely on DTLS-SRTP.

    For Debian 10 buster, these problems have been fixed in version     1:16.28.0~dfsg-0+deb10u4.

    We recommend that you upgrade your asterisk packages.
