Descriptions
GNU Bash through 4.3 bash43-026 does not properly parse function definitions in the values of environment variables, which allows remote attackers to execute arbitrary code or cause a denial of service (uninitialized memory access, and untrusted-pointer read and write operations) 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 and CVE-2014-7169.
GNU Bash hasta 4.3 bash43-026 no analiza debidamente las definiciones de funciones en los valores de las variables de entornos, lo que permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (acceso a memoria no inicializada, y operaciones de leer y escribir de puntero no confiables) a través de un entorno manipulado, como fue demostrado por vectores que involucran la característica ForceCommand en OpenSSH sshd, los módulos mod_cgi y mod_cgid en el servidor de Apache HTTP , secuencias de comandos ejecutados por clientes DHCP no especificados, y otras situaciones en que la configuración del entorno ocurre cruzando un límite de privilegios de la ejecución de Bash. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2014-6271 y CVE-2014-7169.
DNS reverse lookups can be used as a vector of attack for the bash shellshock vulnerability.
