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.

Published: September 27, 2016; 11:59:12 AM -04:00
V3.0: 7.5 HIGH
    V2: 5.0 MEDIUM
CVE-2015-3308

Double free vulnerability in lib/x509/x509_ext.c in GnuTLS before 3.3.14 allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted CRL distribution point.

Published: September 02, 2015; 10:59:01 AM -04:00
    V2: 7.5 HIGH
CVE-2014-8155

GnuTLS before 2.9.10 does not verify the activation and expiration dates of CA certificates, which allows man-in-the-middle attackers to spoof servers via a certificate issued by a CA certificate that is (1) not yet valid or (2) no longer valid.

Published: August 14, 2015; 02:59:01 PM -04:00
    V2: 4.3 MEDIUM
CVE-2015-0282

GnuTLS before 3.1.0 does not verify that the RSA PKCS #1 signature algorithm matches the signature algorithm in the certificate, which allows remote attackers to conduct downgrade attacks via unspecified vectors.

Published: March 24, 2015; 01:59:04 PM -04:00
    V2: 5.0 MEDIUM
CVE-2014-3469

The (1) asn1_read_value_type and (2) asn1_read_value functions in GNU Libtasn1 before 3.6 allows context-dependent attackers to cause a denial of service (NULL pointer dereference and crash) via a NULL value in an ivalue argument.

Published: June 05, 2014; 04:55:06 PM -04:00
    V2: 4.3 MEDIUM
CVE-2014-3468

The asn1_get_bit_der function in GNU Libtasn1 before 3.6 does not properly report an error when a negative bit length is identified, which allows context-dependent attackers to cause out-of-bounds access via crafted ASN.1 data.

Published: June 05, 2014; 04:55:06 PM -04:00
    V2: 6.8 MEDIUM
CVE-2014-3467

    V2: 6.8 MEDIUM
CVE-2014-1959

lib/x509/verify.c in GnuTLS before 3.1.21 and 3.2.x before 3.2.11 treats version 1 X.509 certificates as intermediate CAs, which allows remote attackers to bypass intended restrictions by leveraging a X.509 V1 certificate from a trusted CA to issue new certificates.

Published: March 06, 2014; 07:10:57 PM -05:00
    V2: 5.8 MEDIUM
CVE-2014-0092

lib/x509/verify.c in GnuTLS before 3.1.22 and 3.2.x before 3.2.12 does not properly handle unspecified errors when verifying X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers via a crafted certificate.

    V2: 5.8 MEDIUM
CVE-2009-5138

GnuTLS before 2.7.6, when the GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT flag is not enabled, treats version 1 X.509 certificates as intermediate CAs, which allows remote attackers to bypass intended restrictions by leveraging a X.509 V1 certificate from a trusted CA to issue new certificates, a different vulnerability than CVE-2014-1959.

CVE-2013-1619

The TLS implementation in GnuTLS before 2.12.23, 3.0.x before 3.0.28, and 3.1.x before 3.1.7 does not properly consider timing side-channel attacks on a noncompliant MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets, a related issue to CVE-2013-0169.
