CVE-2014-7169 – GNU Bourne-Again Shell (Bash) Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2014-7169
GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact 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. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271. GNU Bash hasta 4.3 bash43-025 procesa cadenas finales después de la definición malformada de funciones en los valores de variables de entorno, lo que permite a atacantes remotos escribir hacia ficheros o posiblemente tener otro impacto desconocido a través de un entorno manipulado, tal y 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 la cual establecer el entorno ocurre a través de un límite privilegiado de la ejecución de Bash. Nota: Esta vulnerabilidad existe debido a una solución incompleta para CVE-2014-6271. It was found that the fix for CVE-2014-6271 was incomplete, and Bash still allowed certain characters to be injected into other environments via specially crafted environment variables. • https://www.exploit-db.com/exploits/34777 https://www.exploit-db.com/exploits/34895 https://www.exploit-db.com/exploits/34839 https://www.exploit-db.com/exploits/36503 https://www.exploit-db.com/exploits/36504 https://www.exploit-db.com/exploits/34766 https://www.exploit-db.com/exploits/35115 https://www.exploit-db.com/exploits/36933 https://www.exploit-db.com/exploits/34765 https://www.exploit-db.com/exploits/34860 https://www.exploit-db.com/exploits/34879 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-228: Improper Handling of Syntactically Invalid Structure •
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') •

D-Bus 1.3.0 through 1.6.x before 1.6.24 and 1.8.x before 1.8.8 allows local users to (1) cause a denial of service (prevention of new connections and connection drop) by queuing the maximum number of file descriptors or (2) cause a denial of service (disconnect) via multiple messages that combine to have more than the allowed number of file descriptors for a single sendmsg call. D-Bus 1.3.0 hasta 1.6.x anterior a 1.6.24 y 1.8.x anterior a 1.8.8 permite a usuarios locales (1) causar una denegación de servicio (prevención de conexiones nuevas y caída de conexión) mediante la creación de una cola del máximo número de descriptores de ficheros o (2) causar una denegación de servicio (desconexión) a través de múltiples mensajes que combinan para tener más que el número permitido de descriptores de ficheros para una llamada única a sendmsg. • http://advisories.mageia.org/MGASA-2014-0395.html http://lists.opensuse.org/opensuse-updates/2014-09/msg00049.html http://secunia.com/advisories/61378 http://www.debian.org/security/2014/dsa-3026 http://www.mandriva.com/security/advisories?name=MDVSA-2015:176 http://www.openwall.com/lists/oss-security/2014/09/16/9 http://www.securitytracker.com/id/1030864 http://www.ubuntu.com/usn/USN-2352-1 https://bugs.freedesktop.org/show_bug.cgi?id=82820 • CWE-399: Resource Management Errors •

Off-by-one error in D-Bus 1.3.0 through 1.6.x before 1.6.24 and 1.8.x before 1.8.8, when running on a 64-bit system and the max_message_unix_fds limit is set to an odd number, allows local users to cause a denial of service (dbus-daemon crash) or possibly execute arbitrary code by sending one more file descriptor than the limit, which triggers a heap-based buffer overflow or an assertion failure. Error por un paso en D-Bus 1.3.0 hasta la versión 1.6.x en versiones anteriores a 1.6.24 y 1.8.x en versiones anteriores a 1.8.8, cuando cuando se ejecuta en sistemas de 64 bits y el límite max_message_unix_fds está establecido en un número impar, permite a usuarios locales provocar una denegación de servicio (caída de dbus-daemon) o posiblemente ejecutar código arbitrario enviando un descriptor de archivo superior al máximo, lo que desencadena un desbordamiento de buffer basado en memoria dinámica o un fallo de aserción. • http://advisories.mageia.org/MGASA-2014-0395.html http://lists.opensuse.org/opensuse-updates/2014-09/msg00049.html http://secunia.com/advisories/61378 http://www.debian.org/security/2014/dsa-3026 http://www.mandriva.com/security/advisories?name=MDVSA-2015:176 http://www.openwall.com/lists/oss-security/2014/09/16/9 http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html http://www.securitytracker.com/id/1030864 http://www.ubuntu.com/usn/USN-2352-1 https • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
