cyrus-sasl (aka Cyrus SASL) 2.1.27 has an out-of-bounds write leading to unauthenticated remote denial-of-service in OpenLDAP via a malformed LDAP packet. The OpenLDAP crash is ultimately caused by an off-by-one error in _sasl_add_string in common.c in cyrus-sasl. cyrus-sasl (también se conoce como Cyrus SASL) versión 2.1.27, presenta una escritura fuera de límites conllevando a una denegación de servicio remota no autenticada en OpenLDAP por medio de un paquete LDAP malformado. El bloqueo de OpenLDAP es causado en última instancia por un error por un paso en la función _sasl_add_string en el archivo common.c en cyrus-sasl. • http://seclists.org/fulldisclosure/2020/Jul/23 http://seclists.org/fulldisclosure/2020/Jul/24 http://www.openwall.com/lists/oss-security/2022/02/23/4 https://github.com/cyrusimap/cyrus-sasl/issues/587 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E https://lists.debian.org/debian-lts-announce/2019/12/msg00027.h • CWE-193: Off-by-one Error CWE-400: Uncontrolled Resource Consumption CWE-787: Out-of-bounds Write •
CVSS: 6.3EPSS: 0%CPEs: 4EXPL: 0CVE-2019-16782 – Possible Information Leak / Session Hijack Vulnerability in Rack
https://notcve.org/view.php?id=CVE-2019-16782
There's a possible information leak / session hijack vulnerability in Rack (RubyGem rack). This vulnerability is patched in versions 1.6.12 and 2.0.8. Attackers may be able to find and hijack sessions by using timing attacks targeting the session id. Session ids are usually stored and indexed in a database that uses some kind of scheme for speeding up lookups of that session id. By carefully measuring the amount of time it takes to look up a session, an attacker may be able to find a valid session id and hijack the session. • http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00016.html http://www.openwall.com/lists/oss-security/2019/12/18/2 http://www.openwall.com/lists/oss-security/2019/12/18/3 http://www.openwall.com/lists/oss-security/2019/12/19/3 http://www.openwall.com/lists/oss-security/2020/04/08/1 http://www.openwall.com/lists/oss-security/2020/04/09/2 https://github.com/rack/rack/commit/7fecaee81f59926b6e1913511c90650e76673b38 https://github.com/rack/rack/securit • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy CWE-208: Observable Timing Discrepancy •
