CVE-2026-8721 (opens in a new tab)How to fix?
There is no fixed version for Echo:latest libcrypt-openssl-pkcs12-perl.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libcrypt-openssl-pkcs12-perl package and not the libcrypt-openssl-pkcs12-perl package as distributed by Echo.
See How to fix? for Echo:latest relevant fixed versions and status.
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.
