CVE-2026-17510
NVD: Crypt::OpenSSL::PKCS12 versions before 1.98 for Perl allow a NULL pointer dereference in print_attribute via a zero length BMPSTRING attribute. NVD: print_attribute() sizes the destination buffer for a BMPSTRING attribute from its declared byte length with Renew(*attribute, length, char). NVD: A zero length attribute makes that a zero size reallocation, which Perl implements as a free returning NULL, so the buffer pointer becomes NULL, the following strncpy copies nothing, and the caller dereferences NULL in the strlen() it passes to newSVpvn().
