CVSS: 8.8EPSS: 0%CPEs: 4EXPL: 0CVE-2017-5130 – chromium-browser: heap overflow in libxml2
https://notcve.org/view.php?id=CVE-2017-5130
An integer overflow in xmlmemory.c in libxml2 before 2.9.5, as used in Google Chrome prior to 62.0.3202.62 and other products, allowed a remote attacker to potentially exploit heap corruption via a crafted XML file. Un desbordamiento de enteros en xmlmemory.c en versiones anteriores a la 2.9.5 de libxml2, tal y como se emplea en Google Chrome, en versiones anteriores a la 62.0.3202.62 y en otros productos, permite que un atacante remoto explote la corrupción de la memoria dinámica (heap) mediante un archivo XML manipulado. A heap overflow flaw was found in the libxml2 library. An application compiled with libxml2 using the vulnerable debug-only function xmlMemoryStrdup could be used by an attacker to crash the application or execute arbitrary code with the permission of the user running the application. • http://bugzilla.gnome.org/show_bug.cgi?id=783026 http://www.securityfocus.com/bid/101482 https://access.redhat.com/errata/RHSA-2017:2997 https://chromereleases.googleblog.com/2017/10/stable-channel-update-for-desktop.html https://crbug.com/722079 https://git.gnome.org/browse/libxml2/commit/?id=897dffbae322b46b83f99a607d527058a72c51ed https://lists.debian.org/debian-lts-announce/2017/11/msg00034.html https://lists.debian.org/debian-lts-announce/2022/04/msg00004.html https://security.gentoo. • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2017-7375
A flaw in libxml2 allows remote XML entity inclusion with default parser flags (i.e., when the caller did not request entity substitution, DTD validation, external DTD subset loading, or default DTD attributes). Depending on the context, this may expose a higher-risk attack surface in libxml2 not usually reachable with default parser flags, and expose content from local files, HTTP, or FTP servers (which might be otherwise unreachable). Un error en libxml2 permite la inclusión de entidades XML con marcas de analizador por defecto (por ejemplo, cuando el "caller" no solicitó la sustitución de entidades, validación DTD, carga de subconjuntos DTD externo o los atributos DTD por defecto). Dependiendo del contexto, esto podría exponer una superficie de ataque de mayor riesgo en libxml2 que, normalmente, no sería accesible mediante marcas de analizador por defecto. Además, podría exponer contenido de archivos locales o de servidores HTTP y FTP (que serían inalcanzables de otra forma). • http://www.securityfocus.com/bid/98877 http://www.securitytracker.com/id/1038623 https://android.googlesource.com/platform/external/libxml2/+/308396a55280f69ad4112d4f9892f4cbeff042aa https://bugzilla.redhat.com/show_bug.cgi?id=1462203 https://git.gnome.org/browse/libxml2/commit/?id=90ccb58242866b0ba3edbef8fe44214a101c2b3e https://security.gentoo.org/glsa/201711-01 https://source.android.com/security/bulletin/2017-06-01 https://www.debian.org/security/2017/dsa-3952 • CWE-611: Improper Restriction of XML External Entity Reference •

Buffer overflow in libxml2 allows remote attackers to execute arbitrary code by leveraging an incorrect limit for port values when handling redirects. Desbordamiento de búfer en libxml2 permite que atacantes remotos ejecuten código arbitrario aprovechando un límite incorrecto para los valores del puerto cuando se gestionan las redirecciones. • http://www.securityfocus.com/bid/98877 http://www.securitytracker.com/id/1038623 https://android.googlesource.com/platform/external/libxml2/+/51e0cb2e5ec18eaf6fb331bc573ff27b743898f4 https://bugzilla.redhat.com/show_bug.cgi?id=1462216 https://git.gnome.org/browse/libxml2/commit/?id=5dca9eea1bd4263bfa4d037ab2443de1cd730f7e https://source.android.com/security/bulletin/2017-06-01 https://www.debian.org/security/2017/dsa-3952 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2016-9318
libxml2 2.9.4 and earlier, as used in XMLSec 1.2.23 and earlier and other products, does not offer a flag directly indicating that the current document may be read but other files may not be opened, which makes it easier for remote attackers to conduct XML External Entity (XXE) attacks via a crafted document. libxml2 2.9.4 y versiones anteriores, como se usa en XMLSec 1.2.23 y versiones anteriores y otros productos, no ofrece un indicador que indique directamente que el documento actual puede ser leido pero otros archivos no pueden ser abiertos, lo que facilita a atacantes remotos llevar a cabo ataques XML External Entity (XXE) a través de un documento manipulado. • http://www.securityfocus.com/bid/94347 https://bugzilla.gnome.org/show_bug.cgi?id=772726 https://github.com/lsh123/xmlsec/issues/43 https://lists.debian.org/debian-lts-announce/2022/04/msg00004.html https://security.gentoo.org/glsa/201711-01 https://usn.ubuntu.com/3739-1 https://usn.ubuntu.com/3739-2 https://access.redhat.com/security/cve/CVE-2016-9318 https://bugzilla.redhat.com/show_bug.cgi?id=1395609 • CWE-611: Improper Restriction of XML External Entity Reference •
CVSS: 10.0EPSS: 1%CPEs: 5EXPL: 0CVE-2016-4658 – libxml2: Use after free via namespace node in XPointer ranges
https://notcve.org/view.php?id=CVE-2016-4658
xpointer.c in libxml2 before 2.9.5 (as used in Apple iOS before 10, OS X before 10.12, tvOS before 10, and watchOS before 3, and other products) does not forbid namespace nodes in XPointer ranges, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free and memory corruption) via a crafted XML document. xpointer.c en libxml2, en versiones anteriores a la 2.9.5 (tal y como se usa en Apple iOS en versiones anteriores a la 10, OS X en versiones anteriores a la 10.12, tvOS en versiones anteriores a la 10 y watchOS en versiones anteriores a la 3 y otros productos) no prohíbe los nodos de espacio de nombre en los rangos XPointer. Esto permite que atacantes remotos ejecuten código arbitrario o provoquen una denegación de servicio (uso de memoria previamente liberada y corrupción de memoria) mediante un documento XML manipulado. A use-after-free flaw was found in the Xpointer implementation of libxml2. An attacker could use this flaw against an application parsing untrusted XML files and compiled with libxml2 to leak small amount of memory data. • http://lists.apple.com/archives/security-announce/2016/Sep/msg00006.html http://lists.apple.com/archives/security-announce/2016/Sep/msg00008.html http://lists.apple.com/archives/security-announce/2016/Sep/msg00010.html http://lists.apple.com/archives/security-announce/2016/Sep/msg00011.html http://www.securityfocus.com/bid/93054 http://www.securitytracker.com/id/1036858 http://www.securitytracker.com/id/1038623 https://git.gnome.org/browse/libxml2/commit/?id=c1d1f7121194036608bf555f08d3062a36fd344b • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-416: Use After Free •
