There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - An issue was discovered in res_pjsip_diversion.c in Sangoma Asterisk before 13.38.0, 14.x through 16.x
    before 16.15.0, 17.x before 17.9.0, and 18.x before 18.1.0. A crash can occur when a SIP message is
    received with a History-Info header that contains a tel-uri, or when a SIP 181 response is received that
    contains a tel-uri in the Diversion header. (CVE-2020-35652)

  - A buffer overflow in res_pjsip_diversion.c in Sangoma Asterisk versions 13.38.1, 16.15.1, 17.9.1, and
    18.1.1 allows remote attacker to crash Asterisk by deliberately misusing SIP 181 responses.
    (CVE-2020-35776)

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - An issue was discovered in Sangoma Asterisk 16.x before 16.16.1, 17.x before 17.9.2, and 18.x before
    18.2.1 and Certified Asterisk before 16.8-cert6. When re-negotiating for T.38, if the initial remote
    response was delayed just enough, Asterisk would send both audio and T.38 in the SDP. If this happened,
    and the remote responded with a declined T.38 stream, then Asterisk would crash. (CVE-2021-26717)

  - A res_pjsip_session crash was discovered in Asterisk Open Source 13.x before 13.37.1, 16.x before 16.14.1,
    17.x before 17.8.1, and 18.x before 18.0.1. and Certified Asterisk before 16.8-cert5. Upon receiving a new
    SIP Invite, Asterisk did not return the created dialog locked or referenced. This caused a gap between the
    creation of the dialog object, and its next use by the thread that created it. Depending on some off-
    nominal circumstances and timing, it was possible for another thread to free said dialog in this gap.
    Asterisk could then crash when the dialog object, or any of its dependent objects, were dereferenced or
    accessed next by the initial-creation thread. Note, however, that this crash can only occur when using a
    connection-oriented protocol (e.g., TCP or TLS, but not UDP) for SIP transport. Also, the remote client
    must be authenticated, or Asterisk must be configured for anonymous calling. (CVE-2020-28327)

  - An issue was discovered in res_pjsip_diversion.c in Sangoma Asterisk before 13.38.0, 14.x through 16.x
    before 16.15.0, 17.x before 17.9.0, and 18.x before 18.1.0. A crash can occur when a SIP message is
    received with a History-Info header that contains a tel-uri, or when a SIP 181 response is received that
    contains a tel-uri in the Diversion header. (CVE-2020-35652)

  - A buffer overflow in res_pjsip_diversion.c in Sangoma Asterisk versions 13.38.1, 16.15.1, 17.9.1, and
    18.1.1 allows remote attacker to crash Asterisk by deliberately misusing SIP 181 responses.
    (CVE-2020-35776)

  - Incorrect access controls in res_srtp.c in Sangoma Asterisk 13.38.1, 16.16.0, 17.9.1, and 18.2.0 and
    Certified Asterisk 16.8-cert5 allow a remote unauthenticated attacker to prematurely terminate secure
    calls by replaying SRTP packets. (CVE-2021-26712)

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

  - An issue was discovered in res_pjsip_diversion.c in Sangoma Asterisk before 13.38.0, 14.x through 16.x
    before 16.15.0, 17.x before 17.9.0, and 18.x before 18.1.0. A crash can occur when a SIP message is
    received with a History-Info header that contains a tel-uri, or when a SIP 181 response is received that
    contains a tel-uri in the Diversion header. (CVE-2020-35652)

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。

  - 在低于 13.38.0的Sangoma Asterisk 、低于 [ 14.x 的 16.15.0Sangoma 16.x Asterisk 、低于 17.x 的 Sangoma Asterisk 、低于 17.9.0的 Sangoma Asterisk和低于 18.1.018.x 的 Sangoma Asterisk中在 res_pjsip_diversion.c 中发现一个问题。当接收到具有包含 tel-uri 的 History-Info 标头的 SIP 消息或当接收到 Diversion 标头中包含 tel-uri 的 SIP 181 响应时会发生崩溃。 (CVE-2020-35652)

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 主機上安裝了一個或多個受到弱點影響的套件，且廠商未提供可用的修補程式。

  - 在 13.38.0之前的 16.15.0之前、 16.x [] 之前的 14.x 至[]、 17.x 之前的 17.9.0之前的 [] 和 18.x ] 之前的 18.1.0的 Sangoma Asterisk 中的 res_pjsip_diversion.c 發現一個問題。當接收到的 SIP 訊息具有包含 tel-uri 的 History-Info 標頭時或當接收到在轉移標頭中包含 tel-uri 的 SIP 181 回應時可能會發生當機。 (CVE-2020-35652)

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

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。

  - より前の Sangoma Asterisk、 13.38.014.x より前の 16.x16.15.0、 17.x より前の 17.9.0]、[ 18.x より前の 18.1.0の Sangoma Asterisk の res_pjsip_diversion.c に問題が見つかりました。SIP メッセージが tel-uri を含む History-Info ヘッダーと共に受信される際、または Diversion ヘッダーに tel-uri を含む SIP 181 応答が受信される際に、クラッシュが発生する可能性があります。CVE-2020-35652

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.

  - An issue was discovered in res_pjsip_diversion.c in Sangoma Asterisk before 13.38.0, 14.x through 16.x     before 16.15.0, 17.x before 17.9.0, and 18.x before 18.1.0. A crash can occur when a SIP message is     received with a History-Info header that contains a tel-uri, or when a SIP 181 response is received that     contains a tel-uri in the Diversion header. (CVE-2020-35652)

Note that Nessus relies on the presence of the package as reported by the vendor.
