CVE-2026-8721

   
Software afectado OPENSSL
 
Crypt::OpenSSL::PKCS12 versions through 1.94 for Perl truncates passwords with embedded NULLs.

Password parameters in PKCS12.xs are declared char *, which routes through Perl's default typemap to SvPV_nolen. The Perl length is discarded.

The C code (or OpenSSL internally) calls strlen() on the buffer. Any password byte at or after the first NULL is silently dropped. Binary / KDF-derived / HMAC-derived passwords lose entropy without any warnings.
