https://notcve.org/view.php?id=CVE-2020-25710
A flaw was found in OpenLDAP in versions before 2.4.56. This flaw allows an attacker who sends a malicious packet processed by OpenLDAP to force a failed assertion in csnNormalize23(). The highest threat from this vulnerability is to system availability. Se encontró un fallo en OpenLDAP en versiones anteriores a 2.4.56. Este fallo permite a un atacante que envía un paquete malicioso procesado por OpenLDAP forzar una afirmación fallida en la función csnNormalize23(). • https://bugzilla.redhat.com/show_bug.cgi?id=1899678 https://git.openldap.org/openldap/openldap/-/commit/ab3915154e69920d480205b4bf5ccb2b391a0a1f#a2feb6ed0257c21c6672793ee2f94eaadc10c72c 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/2020/12/msg00008.html https://security.netapp.com/advisory/ntap-20210716- • CWE-617: Reachable Assertion •

https://notcve.org/view.php?id=CVE-2019-19906
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: 9.1EPSS: 46%CPEs: 34EXPL: 0CVE-2017-9788 – httpd: Uninitialized memory reflection in mod_auth_digest
https://notcve.org/view.php?id=CVE-2017-9788
In Apache httpd before 2.2.34 and 2.4.x before 2.4.27, the value placeholder in [Proxy-]Authorization headers of type 'Digest' was not initialized or reset before or between successive key=value assignments by mod_auth_digest. Providing an initial key with no '=' assignment could reflect the stale value of uninitialized pool memory used by the prior request, leading to leakage of potentially confidential information, and a segfault in other cases resulting in denial of service. En Apache httpd, en versiones anteriores a la 2.2.34 y en versiones 2.4.x anteriores a la 2.4.27, el valor placeholder en cabeceras [Proxy-]Authorization del tipo 'Digest' no se inicializó o reinició antes de o entre las asignaciones sucesivas key=value por mod_auth_digest. Proporcionar una clave inicial sin asignación "=" podría reflejar el valor obsoleto de la memoria agrupada no inicializada utilizada por la petición anterior. Esto podría dar lugar al filtrado de información potencialmente confidencial y, en otros casos, a un fallo de segmentación que daría como resultado una denegación de servicio (DoS) It was discovered that the httpd's mod_auth_digest module did not properly initialize memory before using it when processing certain headers related to digest authentication. • http://www.debian.org/security/2017/dsa-3913 http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.securityfocus.com/bid/99569 http://www.securitytracker.com/id/1038906 https://access.redhat.com/errata/RHSA-2017:2478 https://access.redhat.com/errata/RHSA-2017:2479 https://access.redhat.com/errata/RHSA-2017:2483 https://access.redhat.com/errata/RHSA-2017:2708 https://access.redhat.com/errata/RHSA-2017:2709 https://access.redhat.com/errata/RHS • CWE-20: Improper Input Validation CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-456: Missing Initialization of a Variable •

https://notcve.org/view.php?id=CVE-2016-6325
The Tomcat package on Red Hat Enterprise Linux (RHEL) 5 through 7, JBoss Web Server 3.0, and JBoss EWS 2 uses weak permissions for (1) /etc/sysconfig/tomcat and (2) /etc/tomcat/tomcat.conf, which allows local users to gain privileges by leveraging membership in the tomcat group. El paquete Tomcat en Red Hat Enterprise Linux (RHEL) 5 hasta la versión 7, JBoss Web Server 3.0 y JBoss EWS 2 utiliza permisos débiles para (1) /etc/sysconfig/tomcat y (2) /etc/tomcat/tomcat.conf, lo que permite a usuarios locales obtener privilegios aprovechando su pertenencia al grupo tomcat. It was discovered that the Tomcat packages installed certain configuration files read by the Tomcat initialization script as writeable to the tomcat group. A member of the group or a malicious web application deployed on Tomcat could use this flaw to escalate their privileges. • http://rhn.redhat.com/errata/RHSA-2016-2045.html http://rhn.redhat.com/errata/RHSA-2016-2046.html http://rhn.redhat.com/errata/RHSA-2017-0457.html http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2016-3090545.html http://www.securityfocus.com/bid/93478 https://access.redhat.com/errata/RHSA-2017:0455 https://access.redhat.com/errata/RHSA-2017:0456 https://bugzilla.redhat.com/show_bug.cgi?id=1367447 https://access.redhat.com/security/cve/CVE-2016-6325 • CWE-264: Permissions, Privileges, and Access Controls CWE-284: Improper Access Control •
CVSS: 7.5EPSS: 0%CPEs: 45EXPL: 1CVE-2016-2183 – SSL/TLS: Birthday attack against 64-bit block ciphers (SWEET32)
https://notcve.org/view.php?id=CVE-2016-2183
The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a "Sweet32" attack. Los cifrados DES y Triple DES, como se usan en los protocolos TLS, SSH e IPSec y otros protocolos y productos, tienen una cota de cumpleaños de aproximadamente cuatro mil millones de bloques, lo que facilita a atacantes remotos obtener datos de texto plano a través de un ataque de cumpleaños contra una sesión cifrada de larga duración, según lo demostrado por una sesión HTTPS usando Triple DES en modo CBC, también conocido como un ataque "Sweet32". A flaw was found in the way the DES/3DES cipher was used as part of the TLS/SSL protocol. A man-in-the-middle attacker could use this flaw to recover some plaintext data by capturing large amounts of encrypted traffic between TLS/SSL server and client if the communication used a DES/3DES based ciphersuite. IBM Informix Dynamic Server suffers from dll injection, PHP code injection, and heap buffer overflow vulnerabilities. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00011.h • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
