CVE-2017-20240 (GCVE-0-2017-20240)

Vulnerability from cvelistv5 – Published: 2026-06-12 13:19 – Updated: 2026-06-12 16:59

Title

Crypt::PBKDF2 versions before 0.261630 for Perl are vulnerable to timing attacks

Summary

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.

Severity

5.9 (Medium)

Vulnerability from cvelistv5 – Published: 2026-06-12 14:41 – Updated: 2026-06-12 17:50

Title

Crypt::PBKDF2 versions before 0.261630 for Perl generate insecure random values for salts

Summary

Crypt::PBKDF2 versions before 0.261630 for Perl generate insecure random values for salts. These versions use the built-in rand function, which is predictable and unsuitable for cryptography.

CVE-2026-9641 (GCVE-0-2026-9641)

Vulnerability from cvelistv5 – Published: 2026-06-12 14:57 – Updated: 2026-06-14 14:46

Title

Crypt::PBKDF2 versions before 0.261630 for Perl have a weak default algorithm and number of iterations

Summary

Crypt::PBKDF2 versions before 0.261630 for Perl have a weak default algorithm and number of iterations. The default algorithm is HMAC-SHA1, which should only be used for legacy systems. These versions default to using 1000 iterations. Depending on the chosen algorithm, 220,000 to 1,400,000 iterations should be used.

Severity

5.3 (Medium)
