Due to a mistake in libcurl's WebSocket code, a malicious server can send a particularly crafted packet which makes libcurl get trapped in an endless busy-loop. There is no other way for the application to escape or exit this loop other than killing the thread/process. This might be used to DoS libcurl-using application.

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

  - Due to a mistake in libcurl's WebSocket code, a malicious server can send a particularly crafted packet     which makes libcurl get trapped in an endless busy-loop. There is no other way for the application to     escape or exit this loop other than killing the thread/process. This might be used to DoS libcurl-using     application. (CVE-2025-5399)

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

The version of Tenable.ad installed on the remote host is prior to 3.77.12. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2025-14 advisory.

  - Due to a mistake in libcurl's WebSocket code, a malicious server can send a particularly crafted packet which     makes libcurl get trapped in an endless busy-loop. There is no other way for the application to escape or exit     this loop other than killing the thread/process. (CVE-2025-5399) 

  - Untrusted search path in .NET and Visual Studio allows an unauthorized attacker to execute code over a     network. (CVE-2025-30399)

  - libcurl accidentally skips the certificate verification for QUIC connections when connecting to a host specified     as an IP address in the URL. Therefore, it does not detect impostors or man-in-the-middle attacks. (CVE-2025-4947)

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

The versions of MySQL Server installed on the remote host are affected by a multiple vulnerabilities as referenced in the July 2025 CPU advisory.

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer).  Supported versions that     are affected are 8.0.0-8.0.42, 8.4.0-8.4.5 and  9.0.0-9.3.0. Easily exploitable vulnerability allows high privileged     attacker with network access via multiple protocols to compromise MySQL Server.  Successful attacks of this     vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of     MySQL Server. (CVE-2025-50101)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer).  Supported versions that     are affected are 8.0.0-8.0.42, 8.4.0-8.4.5 and  9.0.0-9.3.0. Easily exploitable vulnerability allows high     privileged attacker with network access via multiple protocols to compromise MySQL Server.  Successful attacks of     this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS)     of MySQL Server. (CVE-2025-50102)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: DDL).  Supported versions that are     affected are 8.0.0-8.0.42, 8.4.0-8.4.5 and  9.0.0-9.3.0. Easily exploitable vulnerability allows high privileged     attacker with network access via multiple protocols to compromise MySQL Server.  Successful attacks of this     vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of MySQL     Server. (CVE-2025-50104)

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

The version of Curl installed on the remote host is is missing security update. It is, therefore, affected by a denial of service vulnerability.

  - Due to a mistake in libcurl's WebSocket code, a malicious server can send a particularly crafted packet     which makes libcurl get trapped in an endless busy-loop. There is no other way for the application to     escape or exit this loop other than killing the thread/process. This might be used to DoS libcurl-using     application. (CVE-2025-5399)

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

The version of curl installed on the remote host is prior to 8.14.1. It is, therefore, affected by a vulnerability as referenced in the SSA:2025-155-01 advisory.

    New curl packages are available for Slackware 15.0 and -current to fix security issues.

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

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