CVE-2026-8721
CVE-2026-8721 updated by NVD
Summary
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.
