[slackware-security]  gnutls (SSA:2025-324-01)

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


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.
