Crypt::OpenSSL::PKCS12 versions through 1.94 for Perl truncates passwords with embedded NULLs_CVE-2026-8721

{
    "lastseen": "",
    "description": "Crypt::OpenSSL::PKCS12 versions through 1.94 for Perl truncates passwords with embedded NULLs.\n\nPassword parameters in PKCS12.xs are declared char *, which routes through Perl's default typemap to SvPV_nolen.  The Perl length is discarded.\n\nThe 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.",
