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-2004-0081
https://notcve.org/view.php?id=CVE-2004-0081
OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool. OpenSSL 0.9.6 anteriores a la 0.9.6d no manejan adecuadamente los tipos de mensajes desconocidos, lo que permite a atacantes remotos causar una denegación de servicios (por bucle infinito), como se demuestra utilizando la herramienta de testeo Codenomicon TLS. • ftp://ftp.sco.com/pub/updates/OpenServer/SCOSA-2004.10/SCOSA-2004.10.txt ftp://patches.sgi.com/support/free/security/advisories/20040304-01-U.asc http://distro.conectiva.com.br/atualizacoes/?id=a&anuncio=000834 http://fedoranews.org/updates/FEDORA-2004-095.shtml http://marc.info/?l=bugtraq&m=107955049331965&w=2 http://marc.info/?l=bugtraq&m=108403850228012&w=2 http://rhn.redhat.com/errata/RHSA-2004-119.html http://secunia.com/advisories/11139 http://security.gen •
CVE-2004-0112
https://notcve.org/view.php?id=CVE-2004-0112
The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read. El código que une SSL/TLS en OpenSSL 0.9.7a, 0.9.7b y 0.9.7c, usando Kerberos, no comprueba adecuadamente la longitud de los tickets de Kerberos, lo que permite que atacantes remotos provoquen una denegación de servicio. • ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2004-005.txt.asc ftp://ftp.sco.com/pub/updates/OpenServer/SCOSA-2004.10/SCOSA-2004.10.txt http://distro.conectiva.com.br/atualizacoes/?id=a&anuncio=000834 http://docs.info.apple.com/article.html?artnum=61798 http://lists.apple.com/archives/security-announce/2005//Aug/msg00001.html http://lists.apple.com/archives/security-announce/2005/Aug/msg00000.html http://lists.apple.com/mhonarc/security-announce/msg00045.html http: • CWE-125: Out-of-bounds Read •
CVE-2004-0079
https://notcve.org/view.php?id=CVE-2004-0079
The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference. La función do_change_cipher_spec en OpenSSL 0.9.6c hasta 0.9.6.k y 0.9.7a hasta 0.9.7c permite que atacantes remotos provoquen una denegación de servicio (caída) mediante una hábil unión SSL/TLS que provoca un puntero nulo. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-04:05.openssl.asc ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2004-005.txt.asc ftp://ftp.sco.com/pub/updates/OpenServer/SCOSA-2004.10/SCOSA-2004.10.txt http://distro.conectiva.com.br/atualizacoes/?id=a&anuncio=000834 http://docs.info.apple.com/article.html?artnum=61798 http://fedoranews.org/updates/FEDORA-2004-095.shtml http://lists.apple.com/archives/security-announce/2005//Aug/msg00001.html http • CWE-476: NULL Pointer Dereference •
