snmp_oid_compare in snmplib/snmp_api.c in Net-SNMP before 5.8 has a NULL Pointer Exception bug that can be used by an unauthenticated attacker to remotely cause the instance to crash via a crafted UDP packet, resulting in Denial of Service. snmp_oid_compare en snmplib/snmp_api.c en Net-SNMP en versiones anteriores a la 5.8 tiene un error de excepción de puntero NULL que puede ser empleado por un atacante no autenticado para provocar el cierre inesperado de la instancia de forma remota mediante un paquete UDP manipulado, lo que resulta en una denegación de servicio (DoS). • https://dumpco.re/blog/net-snmp-5.7.3-remote-dos https://security.netapp.com/advisory/ntap-20181107-0001 https://sourceforge.net/p/net-snmp/code/ci/7ffb8e25a0db851953155de91f0170e9bf8c457d https://sourceforge.net/p/net-snmp/code/ci/f23bcd3ac6ddee5d0a48f9703007ccc738914791 https://www.oracle.com/technetwork/security-advisory/cpuoct2019-5072832.html https://access.redhat.com/security/cve/CVE-2018-18066 https://bugzilla.redhat.com/show_bug.cgi?id=1637572 • CWE-476: NULL Pointer Dereference •

Remotely observable behaviour in auth-gss2.c in OpenSSH through 7.8 could be used by remote attackers to detect existence of users on a target system when GSS2 is in use. NOTE: the discoverer states 'We understand that the OpenSSH developers do not want to treat such a username enumeration (or "oracle") as a vulnerability.' Un comportamiento observable de forma remota en auth-gss2.c en OpenSSH hasta la versión 7.8 podría ser empleado por atacantes remotos para detectar la existencia de usuarios en un sistema objetivo cuando se está empleando GSS2. NOTA: el descubridor indica que "entendemos que los desarrolladores de OpenSSH no quieran tratar tal listado de nombres de usuario (u "oráculo") como una vulnerabilidad". • http://seclists.org/oss-sec/2018/q3/180 http://www.securityfocus.com/bid/105163 https://security.netapp.com/advisory/ntap-20181221-0001 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 5.3EPSS: 2%CPEs: 32EXPL: 18CVE-2018-15473 – OpenSSH < 7.7 - User Enumeration
https://notcve.org/view.php?id=CVE-2018-15473
OpenSSH through 7.7 is prone to a user enumeration vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c. OpenSSH hasta la versión 7.7 es propenso a una vulnerabilidad de enumeración de usuarios debido a que no retrasa el rescate de un usuario de autenticación no válido hasta que el paquete que contiene la petición haya sido analizado completamente. Esto está relacionado con auth2-gss.c, auth2-hostbased.c, y auth2-pubkey.c. A user enumeration vulnerability flaw was found in OpenSSH, though version 7.7. The vulnerability occurs by not delaying bailout for an invalid authenticated user until after the packet containing the request has been fully parsed. • https://www.exploit-db.com/exploits/45939 https://www.exploit-db.com/exploits/45233 https://www.exploit-db.com/exploits/45210 https://github.com/Rhynorater/CVE-2018-15473-Exploit https://github.com/r3dxpl0it/CVE-2018-15473 https://github.com/Sait-Nuri/CVE-2018-15473 https://github.com/LINYIKAI/CVE-2018-15473-exp https://github.com/MrDottt/CVE-2018-15473 https://github.com/yZ1337/CVE-2018-15473 https://github.com/1stPeak/CVE-2018-15473 https://github.com/0xrobiu • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVSS: 7.5EPSS: 94%CPEs: 2EXPL: 0CVE-2018-8011 – mod_md, DoS via Coredumps on specially crafted requests
https://notcve.org/view.php?id=CVE-2018-8011
By specially crafting HTTP requests, the mod_md challenge handler would dereference a NULL pointer and cause the child process to segfault. This could be used to DoS the server. Fixed in Apache HTTP Server 2.4.34 (Affected 2.4.33). Manipulando especialmente peticiones HTTP, el manipulador challenge mod_md desreferencia un puntero NULL y hace que el proceso hijo entre en segfault. Esto podría emplearse para provocar una denegación de servicio (DoS) en el servidor. • http://www.securitytracker.com/id/1041401 https://httpd.apache.org/security/vulnerabilities_24.html#CVE-2018-8011 https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/84a3714f0878781f6ed84473d1a503d2cc382277e100450209231830%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/r03ee478b3dda3e381fd6189366fa7af97c980d2f602846eef935277d%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/r06f0d87ebb6d59ed8379633f36f72f5b1f79cadfda72ede0830b42cf&# • CWE-476: NULL Pointer Dereference •

Vulnerability in the Java SE component of Oracle Java SE (subcomponent: Windows DLL). Supported versions that are affected are Java SE: 7u181 and 8u172. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java SE, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Java SE. • http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html http://www.securityfocus.com/bid/104781 http://www.securitytracker.com/id/1041302 https://security.netapp.com/advisory/ntap-20180726-0001 •
