OpenVPN 2.1 until v2.4.12 and v2.5.6 may enable authentication bypass in external authentication plug-ins when more than one of them makes use of deferred authentication replies, which allows an external user to be granted access with only partially correct credentials. OpenVPN versiones 2.1 hasta v2.4.12 y versión v2.5.6, puede permitir una omisión de autenticación en los complementos de autenticación externa cuando más de uno de ellos hace uso de las respuestas de autenticación diferida, lo que permite que sea concedido acceso a un usuario externo con credenciales sólo parcialmente correctas • https://community.openvpn.net/openvpn/wiki/CVE-2022-0547 https://community.openvpn.net/openvpn/wiki/SecurityAnnouncements https://lists.debian.org/debian-lts-announce/2022/05/msg00002.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GFXJ35WKPME4HYNQCQNAJHLCZOJL2SAE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/R36OYC5SJ6FLPVAYJYYT4MOJ2I7MGYFF https://openvpn.net/community-downloads • CWE-287: Improper Authentication CWE-305: Authentication Bypass by Primary Weakness •
CVE-2022-27191 – golang: crash in a golang.org/x/crypto/ssh server
https://notcve.org/view.php?id=CVE-2022-27191
The golang.org/x/crypto/ssh package before 0.0.0-20220314234659-1baeb1ce4c0b for Go allows an attacker to crash a server in certain circumstances involving AddHostKey. El paquete golang.org/x/crypto/ssh anterior a 0.0.0-20220314234659-1baeb1ce4c0b para Go permite a un atacante bloquear un servidor en ciertas circunstancias que implican AddHostKey A broken cryptographic algorithm flaw was found in golang.org/x/crypto/ssh. This issue causes a client to fail authentication with RSA keys to servers that reject signature algorithms based on SHA-2, enabling an attacker to crash the server, resulting in a loss of availability. • https://groups.google.com/g/golang-announce https://groups.google.com/g/golang-announce/c/-cp44ypCT5s https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DLUJZV3HBP56ADXU6QH2V7RNYUPMVBXQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/EZ3S7LB65N54HXXBCB67P4TTOHTNPP5O https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HHGBEGJ54DZZGTXFUQNS7ZIG3E624YAF https://lists.fedoraproject.org/archives/list/package-announce%40lis • CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
CVE-2022-24302 – python-paramiko: Race condition in the write_private_key_file function
https://notcve.org/view.php?id=CVE-2022-24302
In Paramiko before 2.10.1, a race condition (between creation and chmod) in the write_private_key_file function could allow unauthorized information disclosure. En Paramiko versiones anteriores a 2.10.1, una condición de carrera (entre creation y chmod) en la función write_private_key_file podría permitir una divulgación de información no autorizada A race condition was found in Paramiko. This flaw allows unauthorized information disclosure from an attacker with access to the write_private_key_file. • https://github.com/paramiko/paramiko/blob/363a28d94cada17f012c1604a3c99c71a2bda003/paramiko/pkey.py#L546 https://lists.debian.org/debian-lts-announce/2022/03/msg00032.html https://lists.debian.org/debian-lts-announce/2022/09/msg00013.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LUEUEGILZ7MQXRSUF5VMMO4SWJQVPTQL https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TPMKRUS4HO3P7NR7P4Y6CLHB4MBEE3AI https://lists.fedoraproject.org/archives/list/package& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2022-0396 – DoS from specifically crafted TCP packets
https://notcve.org/view.php?id=CVE-2022-0396
BIND 9.16.11 -> 9.16.26, 9.17.0 -> 9.18.0 and versions 9.16.11-S1 -> 9.16.26-S1 of the BIND Supported Preview Edition. Specifically crafted TCP streams can cause connections to BIND to remain in CLOSE_WAIT status for an indefinite period of time, even after the client has terminated the connection. BIND versiones 9.16.11 posteriores a 9.16.26, versiones 9.17.0 posteriores a 9.18.0 y versiones 9.16.11-S1 posteriores a 9.16.26-S1 de BIND Supported Preview Edition. Los flujos TCP específicamente diseñados pueden causar que las conexiones a BIND permanezcan en estado CLOSE_WAIT durante un período de tiempo indefinido, incluso después de que el cliente haya terminado la conexión A flaw was found in Bind that incorrectly handles certain crafted TCP streams. The vulnerability allows TCP connection slots to be consumed for an indefinite time frame via a specifically crafted TCP stream sent from a client. • https://cert-portal.siemens.com/productcert/pdf/ssa-637483.pdf https://kb.isc.org/v1/docs/cve-2022-0396 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NYD7US4HZRFUGAJ66ZTHFBYVP5N3OQBY https://security.gentoo.org/glsa/202210-25 https://security.netapp.com/advisory/ntap-20220408-0001 https://access.redhat.com/security/cve/CVE-2022-0396 https://bugzilla.redhat.com/show_bug.cgi?id=2064513 • CWE-404: Improper Resource Shutdown or Release CWE-459: Incomplete Cleanup •
CVE-2021-25220 – DNS forwarders - cache poisoning vulnerability
https://notcve.org/view.php?id=CVE-2021-25220
BIND 9.11.0 -> 9.11.36 9.12.0 -> 9.16.26 9.17.0 -> 9.18.0 BIND Supported Preview Editions: 9.11.4-S1 -> 9.11.36-S1 9.16.8-S1 -> 9.16.26-S1 Versions of BIND 9 earlier than those shown - back to 9.1.0, including Supported Preview Editions - are also believed to be affected but have not been tested as they are EOL. The cache could become poisoned with incorrect records leading to queries being made to the wrong servers, which might also result in false information being returned to clients. BIND versiones 9.11.0 posteriores a 9.11.36, versiones 9.12.0 posteriores a 9.16.26, versiones 9.17.0 posteriores a 9.18.0, Ediciones Preliminares Soportadas con BIND: versiones .11.4-S1 posteriores a 9.11.36-S1, versiones 9.16.8-S1 posteriores a 9.16.26-S1, también creemos que las versiones de BIND 9 anteriores a las mostradas - hasta la versión 9.1.0, incluyendo las ediciones preliminares soportadas - también están afectadas pero no han sido probadas ya que son EOL. La caché podría envenenarse con registros incorrectos, conllevando a una realización de consultas a servidores erróneos, lo que también podría resultar en que se devolviera información falsa a clientes A cache poisoning vulnerability was found in BIND when using forwarders. Bogus NS records supplied by the forwarders may be cached and used by name if it needs to recurse for any reason. • https://cert-portal.siemens.com/productcert/pdf/ssa-637483.pdf https://kb.isc.org/v1/docs/cve-2021-25220 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2SXT7247QTKNBQ67MNRGZD23ADXU6E5U https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5VX3I2U3ICOIEI5Y7OYA6CHOLFMNH3YQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/API7U5E7SX7BAAVFNW366FFJGD6NZZKV https://lists.fedoraproject.org/archives/list/package-announc • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
