New gnutls packages for Slackware fix low-severity security issues. Upgrade recommended for system integrity.
New gnutls packages are available for Slackware 15.0 and -current to fix security issues

Summary

Here are the details from the Slackware 15.0 ChangeLog: patches/packages/gnutls-3.8.11-i586-1_slack15.0.txz: Upgraded. This update fixes a security issue: libgnutls: Fix stack overwrite in gnutls_pkcs11_token_init. Reported by Luigino Camastra from Aisle Research. Upstream says this is low severity because the PKCS#11 standard defines a size limit of 32 characters, and therefore it's the application's fault if it doesn't check that and reject a longer label. I'm not buying that. NOTE: Be sure to also install the nettle upgrade. For more information, see: https://www.cve.org/CVERecord?id=CVE-2025-9820 (* Security fix *) patches/packages/nettle-3.10.2-i586-1_slack15.0.txz: Upgraded. This update is required by gnutls-3.8.11.
