When doing SSH-based transfers using either SCP or SFTP, and asked to do public key authentication, curl would wrongly still ask and authenticate using a locally running SSH agent.

An update of the curl package has been released.

According to its self-reported version, the Nessus Network Monitor running on the remote host is prior to 6.5.3. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2026-02 advisory.

  - A vulnerability was found in SQLite SQLite3 up to 3.43.0 and classified as critical. This issue affects     the function sessionReadRecord of the file ext/session/sqlite3session.c of the component make alltest     Handler. The manipulation leads to heap-based buffer overflow. It is recommended to apply a patch to fix     this issue. The associated identifier of this vulnerability is VDB-248999. (CVE-2023-7104)

  - A use-after-free vulnerability was found in libxml2. This issue occurs when parsing XPath elements under     certain circumstances when the XML schematron has the <sch:name path=.../> schema elements. This flaw     allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the     program's crash using libxml or other possible undefined behaviors. (CVE-2025-49794)

  - A vulnerability was found in libxml2. Processing certain sch:name elements from the input XML file can     trigger a memory corruption issue. This flaw allows an attacker to craft a malicious XML input file that     can lead libxml to crash, resulting in a denial of service or other possible undefined behavior due to     sensitive data being corrupted in memory. (CVE-2025-49796)

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-2026-004929 advisory.

    When doing SSH-based transfers using either SCP or SFTP, and asked to do     public key authentication, curl would wrongly still ask and authenticate using     a locally running SSH agent.

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

The version of curl installed on the remote host is 7.58 <= 8.17.0. It is, therefore, affected by multiple vulnerabilities when built with the libssh backend:

- A key passphrase bypass vulnerability exists where curl wrongly authenticates using a locally   running SSH agent even when specifically asked to perform public key authentication.   (CVE-2025-15224)

- A global known_hosts override vulnerability exists where libcurl may mistakenly accept connections   to hosts not present in a specified known_hosts file if they are recognized in the libssh global   known_hosts file. (CVE-2025-15079)

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

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:20031-1 advisory.

    This update for curl fixes the following issues:

    - CVE-2025-14017: broken TLS options for threaded LDAPS (bsc#1256105).
    - CVE-2025-14524: bearer token leak on cross-protocol redirect (bsc#1255731).
    - CVE-2025-14819: libssh global knownhost override (bsc#1255732).
    - CVE-2025-15079: libssh key passphrase bypass without agent set (bsc#1255733).
    - CVE-2025-15224: OpenSSL partial chain store policy bypass (bsc#1255734).

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

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:0052-1 advisory.

    - CVE-2025-14524: bearer token leak on cross-protocol redirect (bsc#1255731).
    - CVE-2025-14819: libssh global knownhost override (bsc#1255732).
    - CVE-2025-15079: libssh key passphrase bypass without agent set (bsc#1255733).

    - CVE-2025-14524: bearer token leak on cross-protocol redirect (bsc#1255731).
    - CVE-2025-14819: libssh global knownhost override (bsc#1255732).

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

  - When doing SSH-based transfers using either SCP or SFTP, and asked to do public key authentication, curl     would wrongly still ask and authenticate using a locally running SSH agent. (CVE-2025-15224)

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