Stack-based buffer overflow in the cdk_pk_get_keyid function in lib/opencdk/pubkey.c in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allows remote attackers to have unspecified impact via a crafted OpenPGP certificate.

CVSS: 7.5EPSS: 0%CPEs: 5EXPL: 0CVE-2016-7444 – gnutls: Incorrect certificate validation when using OCSP responses (GNUTLS-SA-2016-3)
https://notcve.org/view.php?id=CVE-2016-7444
The gnutls_ocsp_resp_check_crt function in lib/x509/ocsp.c in GnuTLS before 3.4.15 and 3.5.x before 3.5.4 does not verify the serial length of an OCSP response, which might allow remote attackers to bypass an intended certificate validation mechanism via vectors involving trailing bytes left by gnutls_malloc. La función gnutls_ocsp_resp_check_crt en lib/x509/ocsp.c en GnuTLS en versiones anteriores a 3.4.15 y 3.5.x en versiones anteriores a 3.5.4 no verifica la longitud de serie de una respuesta OCSP, lo que podría permitir a atacantes remotos eludir un mecanismo de validación destinada a certificados a través de vectores que involucran bytes finales dejados por gnutls_malloc. A flaw was found in the way GnuTLS validated certificates using OCSP responses. This could falsely report a certificate as valid under certain circumstances. • http://lists.opensuse.org/opensuse-security-announce/2017-02/msg00005.html http://www.securityfocus.com/bid/92893 https://access.redhat.com/errata/RHSA-2017:2292 https://gitlab.com/gnutls/gnutls/commit/964632f37dfdfb914ebc5e49db4fa29af35b1de9 https://lists.gnupg.org/pipermail/gnutls-devel/2016-September/008146.html https://www.gnutls.org/security.html https://access.redhat.com/security/cve/CVE-2016-7444 https://bugzilla.redhat.com/show_bug.cgi?id=1374266 • CWE-264: Permissions, Privileges, and Access Controls CWE-295: Improper Certificate Validation •
