Vulnerability CVE-2010-0731

Vulnerability Name:

CVE-2010-0731 (CCN-57198)

Assigned:

2010-03-25

Published:

2010-03-25

Updated:

2017-09-19

Summary:

The gnutls_x509_crt_get_serial function in the GnuTLS library before 1.2.1, when running on big-endian, 64-bit platforms, calls the asn1_read_value with a pointer to the wrong data type and the wrong length value, which allows remote attackers to bypass the certificate revocation list (CRL) check and cause a stack-based buffer overflow via a crafted X.509 certificate, related to extraction of a serial number.
