Summary
[none]
Details

Crypt::OpenSSL::X509 versions before 2.1.3 for Perl allow denial of service via NULL pointer dereference. X509V3EXTd2i(ext) 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, 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.
