CVE-2017-20240

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...

CVE-2017-20240

The Crypt::PBKDF2 Perl module (versions before 0.261630 ) is vulnerable to timing attacks because it utilizes Perl's built-in eq comparison. An attacker could exploit timing discrepancies to guess the underlying derived-key . This issue affects distributions including Amazon Linux 2023 , Fedora 4...

Unbounded SCRAM iteration count allows a malicious server to cause CPU-exhaustion denial of service

A malicious, compromised, or man-in-the-middle server can supply an arbitrarily large SCRAM-SHA-256 PBKDF2 iteration count during authentication. The client runs it inline with no upper bound, pinning a tokio worker thread for minutes per connection, possibly stalling the whole async runtime...

SUSE CVE-2026-10143

kafka-python prior to 2.3.2 contains a denial-of-service vulnerability in SCRAM authentication handling that allows a malicious or machine-in-the-middle broker to freeze the client event loop by supplying an excessively large iteration count. In scram.py, ScramClient.processserverfirstmessage...

PT-2026-48920

Name of the Vulnerable Software and Affected Versions Crypt::PBKDF2 versions prior to 0.261630 Description Crypt::PBKDF2 for Perl generates insecure random values for salts. This occurs because the software utilizes the built-in rand function, which is predictable and unsuitable for cryptographic...

CVE-2026-9641: Use of Password Hash With Insufficient Computational Effort

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...

CVE-2026-10143

CVE-2026-10143 affects kafka-python prior to 2.3.2. The denial‑of‑service arises from ScramClient.process_server_first_message() passing the broker‑provided SCRAM iteration count directly to hashlib.pbkdf2_hmac() without validation in scram.py. This can freeze the client event loop, blocking prod...

kafka-python prior to 2.3.2 contains a denial-of-service vulnerability in SCRAM authentication handling that allows a malicious or machine-in-the-middle broker to freeze the client event loop by supplying an excessively large iteration count. In scram.py, ScramClient.processserverfirstmessage...

CVE-2026-48859

The CVE affects Erlang/OTP’s SSH server (ssh_auth and ssh_options) in OTP prior to 29.0.2 (SSH 6.0.x before 6.0.1). When the daemon uses user_passwords or password options, ssh_auth:check_password/3 performs PBKDF2-SHA256 with 600,000 iterations (~300 ms) for valid usernames, but returns in ~0 ms...
