Crypt::OpenSSL::X509 versions before 2.1.3 for Perl allow denial of service via NULL pointer dereference. X509V3EXTd2iext returns NULL when an extension's DER value fails to parse. basicC, ia5string, and authatt dereference its result without a NULL check. keyiddata also dereferences akid-keyid,...
