7.5
2017-04-14 CVE-2017-7869 Out-of-bounds Write vulnerability in GNU Gnutls
GnuTLS before 2017-02-20 has an out-of-bounds write caused by an integer overflow and heap-based buffer overflow related to the cdk_pkt_read function in opencdk/read-packet.c.

low complexity
gnu CWE-787
7.5
2017-03-24 CVE-2017-5337 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
Multiple heap-based buffer overflows in the read_attribute function in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allow remote attackers to have unspecified impact via a crafted OpenPGP certificate.

2017-03-24 CVE-2017-5336 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
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.

2017-03-24 CVE-2017-5335 Out-of-bounds Read vulnerability in multiple products
The stream reading functions in lib/opencdk/read-packet.c in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allow remote attackers to cause a denial of service (out-of-memory error and crash) via a crafted OpenPGP certificate.

2017-03-24 CVE-2017-5334 Double Free vulnerability in multiple products
Double free vulnerability in the gnutls_x509_ext_import_proxy function in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allows remote attackers to have unspecified impact via crafted policy language information in an X.509 certificate with a Proxy Certificate Information extension.

2016-09-27 CVE-2016-7444 Permissions, Privileges, and Access Controls vulnerability in GNU Gnutls
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.

low complexity
gnu CWE-264
7.5
2008-11-13 CVE-2008-4989 Improper Certificate Validation vulnerability in multiple products
The _gnutls_x509_verify_certificate function in lib/x509/verify.c in libgnutls in GnuTLS before 2.6.1 trusts certificate chains in which the last certificate is an arbitrary trusted, self-signed certificate, which allows man-in-the-middle attackers to insert a spoofed certificate for any Distinguished Name (DN).
