"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.");
