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

  - A Buffer Overflow issue was discovered in Asterisk through 13.19.1, 14.x through 14.7.5, and 15.x through
    15.2.1, and Certified Asterisk through 13.18-cert2. When processing a SUBSCRIBE request, the
    res_pjsip_pubsub module stores the accepted formats present in the Accept headers of the request. This
    code did not limit the number of headers it processed, despite having a fixed limit of 32. If more than 32
    Accept headers were present, the code would write outside of its memory and cause a crash. (CVE-2018-7284)

  - A NULL pointer access issue was discovered in Asterisk 15.x through 15.2.1. The RTP support in Asterisk
    maintains its own registry of dynamic codecs and desired payload numbers. While an SDP negotiation may
    result in a codec using a different payload number, these desired ones are still stored internally. When
    an RTP packet was received, this registry would be consulted if the payload number was not found in the
    negotiated SDP. This registry was incorrectly consulted for all packets, even those which are dynamic. If
    the payload number resulted in a codec of a different type than the RTP stream (for example, the payload
    number resulted in a video codec but the stream carried audio), a crash could occur if no stream of that
    type had been negotiated. This was due to the code incorrectly assuming that a stream of that type would
    always exist. (CVE-2018-7285)

  - An issue was discovered in Asterisk through 13.19.1, 14.x through 14.7.5, and 15.x through 15.2.1, and
    Certified Asterisk through 13.18-cert2. res_pjsip allows remote authenticated users to crash Asterisk
    (segmentation fault) by sending a number of SIP INVITE messages on a TCP or TLS connection and then
    suddenly closing the connection. (CVE-2018-7286)

  - An issue was discovered in res_http_websocket.c in Asterisk 15.x through 15.2.1. If the HTTP server is
    enabled (default is disabled), WebSocket payloads of size 0 are mishandled (with a busy loop).
    (CVE-2018-7287)

根據其 SIP 標題判斷，遠端主機上執行的 Asterisk 版本是比 15.2.2 舊的 15.x 版。因此，會受到 AST-2018-001、AST-2018-002、AST-2018-003、AST-2018-004、AST-2018-005 與 AST-2018-006 公告中所述多個弱點的影響。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。

根据其 SIP 标题，远程主机上运行的 Asterisk 版本为低于 15.2.2 的 15.x。因此，如 AST-2018-001、AST-2018-002、AST-2018-003、AST-2018-004、AST-2018-005 与 AST-2018-006 公告中所述，受到多个漏洞的影响。请注意，Nessus 并未测试这些问题，而是只依赖于应用程序自我报告的版本号。

SIPバナーによると、リモートホストで実行されているAsteriskのバージョンは、15.2.2より前の15.xです。したがって、AST-2018-001、AST-2018-002、AST-2018-003、AST-2018-004、AST-2018-005、AST-2018-006のアドバイザリに記載されているとおり、複数の脆弱性の影響を受けます。注意：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の自己報告されたバージョン番号のみに依存しています。

According to its SIP banner, the version of Asterisk running on the remote host is 15.x prior to 15.2.2. It is therefore, affected by multiple vulnerabilities as described in AST-2018-001, AST-2018-002, AST-2018-003, AST-2018-004, AST-2018-005, & AST-2018-006 advisories.

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