vulnerabilities as referenced in the SSA:2025-039-01 advisory.

    New gnutls packages are available for Slackware 15.0 and -current to fix a security issue.

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

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