  "description": "Crypt::OpenSSL::X509 versions before 2.1.3 for Perl allow denial of service via NULL pointer dereference.  X509V3_EXT_d2i(ext) returns NULL when an extension\u0027s DER value fails to parse. basicC, ia5string, and auth_att dereference its result without a NULL check. keyid_data also dereferences akid-\u003Ekeyid, which is NULL for an empty AKI SEQUENCE (DER 30 00) even when the parse succeeds.  A caller invoking an affected helper on an extension from an untrusted certificate triggers a SIGSEGV that crashes the Perl process.",
