CVSS: 6.5EPSS: 2%CPEs: 2EXPL: 2CVE-2015-3238 – pam: DoS/user enumeration due to blocking pipe in pam_unix module
https://notcve.org/view.php?id=CVE-2015-3238
18 Aug 2015 — The _unix_run_helper_binary function in the pam_unix module in Linux-PAM (aka pam) before 1.2.1, when unable to directly access passwords, allows local users to enumerate usernames or cause a denial of service (hang) via a large password. Vulnerabilidad en la función _unix_run_helper_binary en el módulo pam_unix en Linux-PAM (también conocido como pam) en versiones anteriores a 1.2.1, cuando no es posible acceder directamente a las contraseñas, permite a usuarios locales enumerar los nombres de usuario o ca... • http://lists.fedoraproject.org/pipermail/package-announce/2015-July/161350.html • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •

CVSS: 4.3EPSS: 94%CPEs: 42EXPL: 1CVE-2015-4000 – LOGJAM: TLS connections which support export grade DHE key-exchange are vulnerable to MITM attacks
https://notcve.org/view.php?id=CVE-2015-4000
21 May 2015 — The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue. El protocolo TLS 1.2 y anteriores, cuando una suite de cifrado DHE_EXPORT está habilitada en un servidor pero no en un cliente, no t... • https://github.com/fatlan/HAProxy-Keepalived-Sec-HighLoads • CWE-310: Cryptographic Issues CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
