A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL pointer dereference) or, for configurations mixing forward and reverse proxy declarations, can allow for requests to be directed to a declared Unix Domain Socket endpoint (Server Side Request Forgery). This issue affects Apache HTTP Server 2.4.7 up to 2.4.51 (included). Un URI diseñado que es enviado a httpd configurado como proxy directo (ProxyRequests on) puede causar un fallo (desreferencia de puntero NULL) o, en el caso de configuraciones que mezclan declaraciones de proxy directo e inverso, puede permitir que las peticiones se dirijan a un endpoint de socket de dominio Unix declarado (Server Side Request Forgery). Este problema afecta a Apache HTTP Server versiones 2.4.7 hasta 2.4.51 (incluyéndola) There's a null pointer dereference and server-side request forgery flaw in httpd's mod_proxy module, when it is configured to be used as a forward proxy. A crafted packet could be sent on the adjacent network to the forward proxy that could cause a crash, or potentially SSRF via misdirected Unix Domain Socket requests. • http://httpd.apache.org/security/vulnerabilities_24.html http://seclists.org/fulldisclosure/2022/May/33 http://seclists.org/fulldisclosure/2022/May/35 http://seclists.org/fulldisclosure/2022/May/38 http://www.openwall.com/lists/oss-security/2021/12/20/3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BFSWOH4X77CV7AH7C4RMHUBDWKQDL4YH https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RGWILBORT67SHMSLYSQZG2NMXGCMPUZO https:// • CWE-476: NULL Pointer Dereference CWE-918: Server-Side Request Forgery (SSRF) •

A security issue in nginx resolver was identified, which might allow an attacker who is able to forge UDP packets from the DNS server to cause 1-byte memory overwrite, resulting in worker process crash or potential other impact. Se identificó un problema de seguridad en el solucionador de nginx, que podría permitir a un atacante que pueda falsificar paquetes UDP desde el servidor DNS para causar una sobrescritura de memoria de 1 byte, lo que causaría un bloqueo del proceso de trabajo u otro impacto potencial A flaw was found in nginx. An off-by-one error while processing DNS responses allows a network attacker to write a dot character out of bounds in a heap allocated buffer which can allow overwriting the least significant byte of next heap chunk metadata likely leading to a remote code execution in certain circumstances. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Nginx version 1.20.0 suffers from a denial of service vulnerability. • https://www.exploit-db.com/exploits/50973 https://github.com/M507/CVE-2021-23017-PoC https://github.com/ShivamDey/CVE-2021-23017 https://github.com/lakshit1212/CVE-2021-23017-PoC http://mailman.nginx.org/pipermail/nginx-announce/2021/000300.html http://packetstormsecurity.com/files/167720/Nginx-1.20.0-Denial-Of-Service.html https://lists.apache.org/thread.html/r37e6b2165f7c910d8e15fd54f4697857619ad2625f56583802004009%40%3Cnotifications.apisix.apache.org%3E https://lists.apache.org/thread.html/r4d4966221ca399 • CWE-193: Off-by-one Error •

An integer overflow in the getnum function in lua_struct.c in Redis before 6.0.3 allows context-dependent attackers with permission to run Lua code in a Redis session to cause a denial of service (memory corruption and application crash) or possibly bypass intended sandbox restrictions via a large number, which triggers a stack-based buffer overflow. NOTE: this issue exists because of a CVE-2015-8080 regression. Un desbordamiento de enteros en la función getnum en el archivo lua_struct.c en Redis versiones anteriores a 6.0.3, permite a atacantes dependiendo del contexto, con permiso para ejecutar el código Lua en una sesión de Redis, causar una denegación de servicio (corrupción de la memoria y bloqueo de la aplicación) o posiblemente omitir las restricciones del sandbox previstas por medio de un número grande, lo que desencadena un desbordamiento de búfer en la región stack de la pila. NOTA: este problema se presenta debido a una regresión de CVE-2015-8080 • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00058.html https://github.com/antirez/redis/commit/ef764dde1cca2f25d00686673d1bc89448819571 https://github.com/antirez/redis/pull/6875 https://security.gentoo.org/glsa/202008-17 https://www.debian.org/security/2020/dsa-4731 https://www.oracle.com/security-alerts/cpujan2021.html • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •

In jQuery versions greater than or equal to 1.0.3 and before 3.5.0, passing HTML containing <option> elements from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code. This problem is patched in jQuery 3.5.0. En jQuery versiones mayores o iguales a 1.0.3 y anteriores a la versión 3.5.0, passing HTML contiene elementos de fuentes no seguras – incluso después de sanearlo – para uno de los métodos de manipulación de jQuery ´s DOM ( i.e. html t(), adjunto (), y otros ) podrían ejecutar códigos no seguros. Este problema está corregido en JQuery 3.5.0.
