When doing TLS related transfers with reused easy or multi handles and altering the `CURLSSLOPT_NO_PARTIALCHAIN` option, libcurl could accidentally reuse a CA store cached in memory for which the partial chain option was reversed. Contrary to the user's wishes and expectations. This could make libcurl find and accept a trust chain that it otherwise would not.

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 version of libcurl installed on the remote host is missing a security update. It is, therefore, affected by a improper certificate validation vulnerability.

  - When performing TLS transfers with reused easy or multi handles and altering the     CURLSSLOPT_NO_PARTIALCHAIN option, libcurl could accidentally reuse a CA store cached in memory for     which the partial chain option was reversed.
