libcrypt-openssl-pkcs12-perl: Crypt::OpenSSL::PKCS12 versions through 1.94 for Perl truncates passwords with embedded NULLs
CVE-2026-8721 is fixed in libcrypt-openssl-pkcs12-perl on 1 platform by DEBIAN-CVE-2026-8721 (version 1.95-1), released May 27, 2026. It is not reported as exploited. Patch Radar priority: Urgent.
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.
