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-2012-2665 – libreoffice: Multiple heap-based buffer overflows in the XML manifest encryption handling code
https://notcve.org/view.php?id=CVE-2012-2665
Multiple heap-based buffer overflows in the XML manifest encryption tag parsing functionality in OpenOffice.org and LibreOffice before 3.5.5 allow remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted Open Document Text (.odt) file with (1) a child tag within an incorrect parent tag, (2) duplicate tags, or (3) a Base64 ChecksumAttribute whose length is not evenly divisible by four. Múltiples desbordamientos de bufer basado en en la funcionalidad de cifrado de manifiesto XML en la etiqueta en OpenOffice.org y LibreOffice anterior a v3.5.5 permite a atacantes remotos causar una denegación de servicio y posiblemente ejecutar código arbitrario a través de un Documento de texto diseñado (. Odt) con el archivo(1) una etiqueta de niño dentro de una etiqueta principal incorrecta, (2) duplicar los tags, o (3) un ChecksumAttribute Base64 cuya longitud no es divisible por cuatro. • http://rhn.redhat.com/errata/RHSA-2012-1135.html http://secunia.com/advisories/50142 http://secunia.com/advisories/50146 http://secunia.com/advisories/50692 http://secunia.com/advisories/60799 http://security.gentoo.org/glsa/glsa-201209-05.xml http://www.debian.org/security/2012/dsa-2520 http://www.gentoo.org/security/en/glsa/glsa-201408-19.xml http://www.libreoffice.org/about-us/security/advisories/cve-2012-2665 http://www.pre-cert.de/advisories/PRE-SA-2012-05 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
