The remote Fedora 42 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2025-16a24364ce advisory.

    This updates gnutls to the latest upstream release. Notable changes are:

    * PKCS#11 cryptographic provider support
    * Support for kTLS rekeying with kernel 6.14+
    * Support for the almost standardized ML-DSA private key formats

    This also fixes 4 CVEs (CVE-2025-32989, CVE-2025-6395, CVE-2025-32988, and CVE-2025-32990).

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

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

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7635-1 advisory.

    It was discovered that GnuTLS incorrectly handled exporting Subject Alternative Name (SAN) entries     containing an otherName. A remote attacker could use this issue to cause GnuTLS to crash, resulting in a     denial of service, or possibly execute arbitrary code. (CVE-2025-32988)

    It was discovered that GnuTLS incorrectly handled parsing the Certificate Transparency (CT) Signed     Certificate Timestamp (SCT) extension. A remote attacker could use this issue to cause GnuTLS to crash,     resulting in a denial of service, or possibly obtain sensitive information. (CVE-2025-32989)

    It was discovered that the GnuTLS certtool utility incorrectly handled parsing certain template files. An     attacker could use this issue to cause GnuTLS to crash, resulting in a denial of service, or possibly     execute arbitrary code. (CVE-2025-32990)

    Stefan Bhler discovered that GnuTLS incorrectly handled parsing certain template files. An attacker     could possibly use this issue to cause GnuTLS to crash, resulting in a denial of service. (CVE-2025-6395)

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

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

An update of the gnutls package has been released.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:02595-1 advisory.

    - CVE-2025-6395: Fix NULL pointer dereference when 2nd Client Hello omits PSK (bsc#1246299)
    - CVE-2025-32988: Fix double-free due to incorrect ownership handling in the export logic of SAN entries     containing an otherName (bsc#1246232)
    - CVE-2025-32989: Fix heap buffer overread when handling the CT SCT extension during X.509 certificate     parsing (bsc#1246233)
    - CVE-2025-32990: Fix 1-byte heap buffer overflow when parsing templates with certtool (bsc#1246267)

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

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 gnutls installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-32988 advisory.

  - A flaw was found in GnuTLS. A double-free vulnerability exists in GnuTLS due to incorrect ownership     handling in the export logic of Subject Alternative Name (SAN) entries containing an otherName. If the     type-id OID is invalid or malformed, GnuTLS will call asn1_delete_structure() on an ASN.1 node it does not     own, leading to a double-free condition when the parent function or caller later attempts to free the same     structure. This vulnerability can be triggered using only public GnuTLS APIs and May result in denial of     service or memory corruption, depending on allocator behavior. (CVE-2025-32988)

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

The remote host is affected by the vulnerability described in GLSA-202509-08 (GnuTLS: Multiple Vulnerabilities)

    Multiple vulnerabilities have been discovered in GnuTLS. Please review the CVE identifiers referenced     below for details.

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

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

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

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