CVSS: 8.4EPSS: 0%CPEs: 4EXPL: 0CVE-2016-7543 – bash: Specially crafted SHELLOPTS+PS4 variables allows command substitution
https://notcve.org/view.php?id=CVE-2016-7543
Bash before 4.4 allows local users to execute arbitrary commands with root privileges via crafted SHELLOPTS and PS4 environment variables. Bash en versiones anteriores a 4.4 permite a usuarios locales ejecutar comandos arbitrarios con privilegios root a través de variables de entorno SHELLOPTS y PS4 manipuladas. An arbitrary command injection flaw was found in the way bash processed the SHELLOPTS and PS4 environment variables. A local, authenticated attacker could use this flaw to exploit poorly written setuid programs to elevate their privileges under certain circumstances. • http://rhn.redhat.com/errata/RHSA-2017-0725.html http://www.openwall.com/lists/oss-security/2016/09/26/9 http://www.securityfocus.com/bid/93183 http://www.securitytracker.com/id/1037812 https://access.redhat.com/errata/RHSA-2017:1931 https://h20566.www2.hpe.com/portal/site/hpsc/public/kb/docDisplay?docId=emr_na-c05388115 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F7XOQSHU63Y357NHU5FPTFBM6I3YOCQB https://lists.fedoraproject.org/archives/list&#x • CWE-20: Improper Input Validation CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •

https://notcve.org/view.php?id=CVE-2016-9401
popd in bash might allow local users to bypass the restricted shell and cause a use-after-free via a crafted address. popd en bash podrían permitir a usuarios locales eludir el shell restringido y provocar un uso después de liberación de memoria a través de una dirección manipulada. A denial of service flaw was found in the way bash handled popd commands. A poorly written shell script could cause bash to crash resulting in a local denial of service limited to a specific bash session. • http://rhn.redhat.com/errata/RHSA-2017-0725.html http://www.openwall.com/lists/oss-security/2016/11/17/5 http://www.openwall.com/lists/oss-security/2016/11/17/9 http://www.securityfocus.com/bid/94398 https://access.redhat.com/errata/RHSA-2017:1931 https://lists.debian.org/debian-lts-announce/2019/03/msg00028.html https://security.gentoo.org/glsa/201701-02 https://access.redhat.com/security/cve/CVE-2016-9401 https://bugzilla.redhat.com/show_bug.cgi?id=1396383 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2016-0634
The expansion of '\h' in the prompt string in bash 4.3 allows remote authenticated users to execute arbitrary code via shell metacharacters placed in 'hostname' of a machine. La expansión de \h en la línea de comandos en bash 4.3 permite a los usuarios autenticados remotos ejecutar código arbitrario mediante metacaracteres shell ubicados en 'hostname' de la máquina. An arbitrary command injection flaw was found in the way bash processed the hostname value. A malicious DHCP server could use this flaw to execute arbitrary commands on the DHCP client machines running bash under specific circumstances. • http://rhn.redhat.com/errata/RHSA-2017-0725.html http://www.openwall.com/lists/oss-security/2016/09/16/12 http://www.openwall.com/lists/oss-security/2016/09/16/8 http://www.openwall.com/lists/oss-security/2016/09/18/11 http://www.openwall.com/lists/oss-security/2016/09/19/7 http://www.openwall.com/lists/oss-security/2016/09/20/1 http://www.openwall.com/lists/oss-security/2016/09/27/9 http://www.openwall.com/lists/oss-security/2016/09/29& • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

https://notcve.org/view.php?id=CVE-2014-6278
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 commands 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, CVE-2014-7169, and CVE-2014-6277. 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 comandos arbitrarios a través de un entorno manipulado, como fue demostrado por vectores involucrando la caracteristica ForceCommand en OpenSSH sshd, los módulos mod_cgi y mod_cgid en el servidor Apache HTTP, secuencias de comandos ejecutadas por clientes DHCP no especificados, y otras situaciones en las cuales la configuración del entorno ocurre tras un límite de privilegios de la ejecución de Bash. NOTA: esta vulnerabilidad existe debido a una solución incompleta para el CVE-2014-6271, CVE-2014-7169, y CVE-2014-6277.
