Zeek test script for CVE-2020-13777 This script performs a simple test to check if a server is potentially vulnerable to CVE-2020-13777. CVE-2020-13777 causes GnuTLS to create unencrypted session tickets. This seems to be detectable by checking gnutls sets the keyname to zero - for which it uses...
cryptodev-linux
cryptodev-linux This is a /dev/crypto device driver, equivalent to those in OpenBSD or FreeBSD. The main idea is to access existing ciphers in kernel space from userspace, thus enabling the re-use of a hardware implementation of a cipher. For questions and suggestions, please use the homepage at...

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Incomplete X.509 implementation in GnuTLS v3.8.13 allows attackers controlling a subordinate Certificate Authority to bypass cross-domain PKI restrictions and...
Linux Distros Unpatched Vulnerability : CVE-2026-67693
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - An issue in gnutls v.3.8.13 allows an attacker to obtain sensitive information via failing to reject end- entity X.509 certificates that contain a contradictory...
Linux Distros Unpatched Vulnerability : CVE-2026-88647
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A hostname verification bypass in GnuTLS v3.8.13 allows attackers to circumvent the Common Name fallback mechanism and eavesdrop on communications via a crafted...
CVE-2026-67693
A flaw was found in GnuTLS. The certificate verification process fails to properly reject end-entity digital certificates containing contradictory Key Usage KU and Extended Key Usage EKU extensions, which define the permitted cryptographic operations of a certificate. A remote attacker could...
CVE-2026-88648
A flaw was found in GnuTLS. An attacker controlling a subordinate Certificate Authority CA can exploit an incomplete X.509 certificate validation mechanism to bypass cross-domain Public Key Infrastructure PKI restrictions. This allows unauthorized certificates to be accepted as valid, potentially...
CVE-2026-88647
A flaw was found in GnuTLS. This vulnerability can lead to information disclosure by allowing an attacker to bypass certificate hostname verification. A remote attacker presenting a crafted certificate can circumvent the Common Name fallback check, enabling them to eavesdrop on or intercept...
