An update of the gnutls package has been released.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the c3e1df74-5e73-11f0-95e5-74563cf9e4e9 advisory.

    Daiki Ueno  reports:

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

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

According to the versions of the gnutls packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    A NULL pointer dereference flaw was found in the GnuTLS software in
    _gnutls_figure_common_ciphersuite().(CVE-2025-6395)

    A heap-buffer-overflow (off-by-one) flaw was found in the GnuTLS software in the template parsing logic     within the certtool utility. When it reads certain settings from a template file, it allows an attacker to     cause an out-of-bounds (OOB) NULL pointer write, resulting in memory corruption and a denial-of-service     (DoS) that could potentially crash the system.(CVE-2025-32990)

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)
