Vulnerability Name:

CVE-2006-7239 (CCN-58849)

Assigned:2006-08-12
Published:2006-08-12
Updated:2023-02-13
Summary:The _gnutls_x509_oid2mac_algorithm function in lib/gnutls_algorithms.c in GnuTLS before 1.4.2 allows remote attackers to cause a denial of service (crash) via a crafted X.509 certificate that uses a hash algorithm that is not supported by GnuTLS, which triggers a NULL pointer dereference.
