CVE-2014-6271 – GNU Bourne-Again Shell (Bash) Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2014-6271
GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute arbitrary code via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution, aka "ShellShock." NOTE: the original fix for this issue was incorrect; CVE-2014-7169 has been assigned to cover the vulnerability that is still present after the incorrect fix. GNU Bash hasta la versión 4.3 procesa cadenas finales después de las definiciones de funciones en los valores de variables de entorno, lo que permite a atacantes remotos ejecutar código arbitrario a través de un entorno manipulado, tal como se ha demostrado por vectores que involucran la característica ForceCommand en sshd OpenSSH, los módulos mod_cgi y mod_cgid en el Apache HTTP Server, scripts ejecutados por clientes DHCP no especificados, y otras situaciones en las cuales el ajuste de entorno ocurre a través de un límite privilegiado de la ejecución de Bash, también conocido como "ShellShock." NOTA: la reparación original para este problema era incorrecta; CVE-2014-7169 ha sido asignada para cubrir la vulnerabilidad que todavía está presente después de la solución incorrecta. A flaw was found in the way Bash evaluated certain specially crafted environment variables. • https://github.com/darrenmartyn/visualdoor https://www.exploit-db.com/exploits/38849 https://www.exploit-db.com/exploits/34777 https://www.exploit-db.com/exploits/39918 https://www.exploit-db.com/exploits/34895 https://www.exploit-db.com/exploits/34839 https://www.exploit-db.com/exploits/40619 https://www.exploit-db.com/exploits/36503 https://www.exploit-db.com/exploits/36504 https://www.exploit-db.com/exploits/40938 https://www.exploit-db.com/exploits/34900 https • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-94: Improper Control of Generation of Code ('Code Injection') •
CVE-2014-3470 – openssl: client-side denial of service when using anonymous ECDH
https://notcve.org/view.php?id=CVE-2014-3470
The ssl3_send_client_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h, when an anonymous ECDH cipher suite is used, allows remote attackers to cause a denial of service (NULL pointer dereference and client crash) by triggering a NULL certificate value. La función ssl3_send_client_key_exchange en s3_clnt.c en OpenSSL anterior a 0.9.8za, 1.0.0 anterior a 1.0.0m y 1.0.1 anterior a 1.0.1h, cuando un suite de cifrado ECDH anónimo está utilizado, permite a atacantes remotos causar una denegación de servicio (referencia a puntero nulo y caída de cliente) mediante la provocación de un valor de certificado nulo. • http://aix.software.ibm.com/aix/efixes/security/openssl_advisory9.asc http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10629 http://kb.juniper.net/InfoCenter/index?page=content&id=KB29195 http://lists.fedoraproject.org/pipermail/package-announce/2014-August/136470.html http://lists.fedoraproject.org/pipermail/package-announce/2014-August/136473.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00016.html • CWE-476: NULL Pointer Dereference •
CVE-2014-0221 – openssl: DoS when sending invalid DTLS handshake
https://notcve.org/view.php?id=CVE-2014-0221
The dtls1_get_message_fragment function in d1_both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h allows remote attackers to cause a denial of service (recursion and client crash) via a DTLS hello message in an invalid DTLS handshake. La función dtls1_get_message_fragment en d1_both.c en OpenSSL anterior a 0.9.8za, 1.0.0 anterior a 1.0.0m y 1.0.1 anterior a 1.0.1h permite a atacantes remotos causar una denegación de servicio (recursión y caída de cliente) a través de un mensaje DTLS hello en una negociación DTLS inválida. A denial of service flaw was found in the way OpenSSL handled certain DTLS ServerHello requests. A specially crafted DTLS handshake packet could cause a DTLS client using OpenSSL to crash. • http://aix.software.ibm.com/aix/efixes/security/openssl_advisory9.asc http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10629 http://linux.oracle.com/errata/ELSA-2014-1053.html http://lists.fedoraproject.org/pipermail/package-announce/2014-August/136470.html http://lists.fedoraproject.org/pipermail/package-announce/2014-August/136473.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00016.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00011.html http: • CWE-400: Uncontrolled Resource Consumption •
CVE-2013-1690 – Mozilla Firefox and Thunderbird Denial-of-Service Vulnerability
https://notcve.org/view.php?id=CVE-2013-1690
Mozilla Firefox before 22.0, Firefox ESR 17.x before 17.0.7, Thunderbird before 17.0.7, and Thunderbird ESR 17.x before 17.0.7 do not properly handle onreadystatechange events in conjunction with page reloading, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted web site that triggers an attempt to execute data at an unmapped memory location. Mozilla Firefox anterior a 22.0, Firefox ESR 17.x anterior a 17.0.7, Thunderbird anterior a 17.0.7, y Thunderbird ESR 17.x anterior a 17.0.7 no manejan adecuadamente los eventos "onreadystatechange" en conjunción con las recargas de página, lo que permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) o posiblemente la ejecución arbitraria de código a través de un sitio web manipulado que provoca un intento de ejecución de datos y una asignación de memoria sin mapear. Mozilla Firefox and Thunderbird do not properly handle onreadystatechange events in conjunction with page reloading, which allows remote attackers to cause a denial-of-service (DoS) or possibly execute malicious code via a crafted web site. • https://www.exploit-db.com/exploits/27429 http://lists.opensuse.org/opensuse-security-announce/2013-07/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2013-07/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2013-07/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2013-07/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2013-07/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2013-07/msg00011.html http://rhn • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
