CVE-2017-12613 – apr: Out-of-bounds array deref in apr_time_exp*() functions
https://notcve.org/view.php?id=CVE-2017-12613
When apr_time_exp*() or apr_os_exp_time*() functions are invoked with an invalid month field value in Apache Portable Runtime APR 1.6.2 and prior, out of bounds memory may be accessed in converting this value to an apr_time_exp_t value, potentially revealing the contents of a different static heap value or resulting in program termination, and may represent an information disclosure or denial of service vulnerability to applications which call these APR functions with unvalidated external input. Cuando las funciones apr_time_exp*() o apr_os_exp_time*() se invocan con un valor del campo no válido en Apache Portable Runtime APR 1.6.2 y anteriores, se podría acceder a la memoria fuera de límites convirtiendo este valor en un valor apr_time_exp_t, revelando potencialmente el contenido de otro valor de memoria dinámica estática. También podría desembocar en la terminación del programa, representando una vulnerabilidad de divulgación de información o de denegación de servicio en aplicaciones que llaman a esas funciones APR con entradas externas no validadas. An out-of-bounds array dereference was found in apr_time_exp_get(). An attacker could abuse an unvalidated usage of this function to cause a denial of service or potentially lead to data leak. • http://www.apache.org/dist/apr/Announcement1.x.html http://www.openwall.com/lists/oss-security/2021/08/23/1 http://www.securityfocus.com/bid/101560 http://www.securitytracker.com/id/1042004 https://access.redhat.com/errata/RHSA-2017:3270 https://access.redhat.com/errata/RHSA-2017:3475 https://access.redhat.com/errata/RHSA-2017:3476 https://access.redhat.com/errata/RHSA-2017:3477 https://access.redhat.com/errata/RHSA-2018:0316 https://access.redhat.com/errata/RHSA • CWE-125: Out-of-bounds Read •
CVE-2016-0742 – nginx: invalid pointer dereference in resolver
https://notcve.org/view.php?id=CVE-2016-0742
The resolver in nginx before 1.8.1 and 1.9.x before 1.9.10 allows remote attackers to cause a denial of service (invalid pointer dereference and worker process crash) via a crafted UDP DNS response. El traductor de direcciones en nginx en versiones anteriores a 1.8.1 y 1.9.x en versiones anteriores a 1.9.10 permite a atacantes remotos provocar una denegación de servicio (referencia a puntero no válido y caída del proceso trabajador) a través de una respuesta UDP DNS manipulada. It was discovered that nginx could perform an out of bound read and dereference an invalid pointer when resolving CNAME DNS records. An attacker able to manipulate DNS responses received by nginx could use this flaw to cause a worker process to crash if nginx enabled the resolver in its configuration. • http://lists.opensuse.org/opensuse-updates/2016-02/msg00042.html http://mailman.nginx.org/pipermail/nginx/2016-January/049700.html http://seclists.org/fulldisclosure/2021/Sep/36 http://www.debian.org/security/2016/dsa-3473 http://www.securitytracker.com/id/1034869 http://www.ubuntu.com/usn/USN-2892-1 https://access.redhat.com/errata/RHSA-2016:1425 https://bto.bluecoat.com/security-advisory/sa115 https://bugzilla.redhat.com/show_bug.cgi?id=1302587 https://security.gentoo • CWE-125: Out-of-bounds Read CWE-476: NULL Pointer Dereference •
CVE-2015-7545 – git: arbitrary code execution via crafted URLs
https://notcve.org/view.php?id=CVE-2015-7545
The (1) git-remote-ext and (2) unspecified other remote helper programs in Git before 2.3.10, 2.4.x before 2.4.10, 2.5.x before 2.5.4, and 2.6.x before 2.6.1 do not properly restrict the allowed protocols, which might allow remote attackers to execute arbitrary code via a URL in a (a) .gitmodules file or (b) unknown other sources in a submodule. El (1) git-remote-ext y (2) otros programas de ayuda remotos no especificados en Git en versiones anteriores a 2.3.10, 2.4.x en versiones anteriores a 2.4.10, 2.5.x en versiones anteriores a 2.5.4 y 2.6.x en versiones anteriores a 2.6.1 no restringen correctamente los protocolos permitidos, lo que podría permitir a atacantes remotos ejecutar código arbitrario a través de una URL en un (a) archivo .gitmodules u (b) otras fuentes desconocidas en un submódulo. A flaw was found in the way the git-remote-ext helper processed certain URLs. If a user had Git configured to automatically clone submodules from untrusted repositories, an attacker could inject commands into the URL of a submodule, allowing them to execute arbitrary code on the user's system. • http://lists.opensuse.org/opensuse-updates/2015-11/msg00066.html http://rhn.redhat.com/errata/RHSA-2015-2515.html http://www.debian.org/security/2016/dsa-3435 http://www.openwall.com/lists/oss-security/2015/12/08/5 http://www.openwall.com/lists/oss-security/2015/12/09/8 http://www.openwall.com/lists/oss-security/2015/12/11/7 http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html http://www.oracle.com/technetwork/topics/security/linuxbulletinjan2016 • CWE-20: Improper Input Validation CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-284: Improper Access Control •
CVE-2014-4650 – Python CGIHTTPServer - Encoded Directory Traversal
https://notcve.org/view.php?id=CVE-2014-4650
The CGIHTTPServer module in Python 2.7.5 and 3.3.4 does not properly handle URLs in which URL encoding is used for path separators, which allows remote attackers to read script source code or conduct directory traversal attacks and execute unintended code via a crafted character sequence, as demonstrated by a %2f separator. El módulo CGIHTTPServer en Python versiones 2.7.5 y 3.3.4, no maneja apropiadamente las URL en las que la codificación de URL es usada para los separadores de ruta, lo que permite a atacantes remotos leer el código fuente del script o conducir un salto de directorio y ejecutar código no deseado por medio de una secuencia de caracteres diseñada, como es demostrado mediante un separador %2f. It was discovered that the CGIHTTPServer module incorrectly handled URL encoded paths. A remote attacker could use this flaw to execute scripts outside of the cgi-bin directory, or disclose source of scripts in the cgi-bin directory. • https://www.exploit-db.com/exploits/33894 http://bugs.python.org/issue21766 http://openwall.com/lists/oss-security/2014/06/26/3 https://access.redhat.com/security/cve/cve-2014-4650 https://access.redhat.com/security/cve/CVE-2014-4650 https://bugzilla.redhat.com/show_bug.cgi?id=1113527 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-138: Improper Neutralization of Special Elements •
