Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2017-20240 not yet assigned priority: Debian including 1 source packages (libcrypt-pbkdf2-perl), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): open 3, resolved 2.
Crypt::PBKDF2 versions before 0.261630 for Perl are vulnerable to timing attacks. These versions use Perl's built-in eq comparison. Discrepancies in timing could be used to guess the underlying derived-key.
