The remote SUSE Linux SLES12 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2025:02521-1 advisory.

    - 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 this issue but has instead relied only on the application's self-reported version number.

The version of gnutls installed on the remote host is prior to 3.3.29-9. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-2969 advisory.

    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 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).
