A heap-buffer-overread vulnerability was found in GnuTLS in how it handlesthe Certificate Transparency (CT) Signed Certificate Timestamp (SCT)extension during X.509 certificate parsing. This flaw allows a malicioususer to create a certificate containing a malformed SCT extension (OID1.3.6.1.4.1.11129.2.4.2) that contains sensitive data. This issue leads tothe exposure of confidential information when GnuTLS verifies certificatesfrom certain websites when the certificate (SCT) is not checked correctly.
