https://notcve.org/view.php?id=CVE-2017-8872
The htmlParseTryOrFinish function in HTMLparser.c in libxml2 2.9.4 allows attackers to cause a denial of service (buffer over-read) or information disclosure. La función htmlParseTryOrFinish en HTMLparser.c en libxml2 2.9.4 permite a los atacantes causar una denegación de servicio (sobrelectura de búfer) o divulgación de información. • https://bugzilla.gnome.org/show_bug.cgi?id=775200 https://lists.debian.org/debian-lts-announce/2020/09/msg00009.html • CWE-125: Out-of-bounds Read •
CVE-2017-5969
https://notcve.org/view.php?id=CVE-2017-5969
libxml2 2.9.4, when used in recover mode, allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted XML document. NOTE: The maintainer states "I would disagree of a CVE with the Recover parsing option which should only be used for manual recovery at least for XML parser. ** DISPUTADO ** libxml2 2.9.4, cuando se utiliza en el modo de recuperación, permite a los atacantes remotos provocar una denegación de servicio (referencia de puntero NULL) por medio de un documento XML manipulado. NOTA: El mantenedor declara que "no estaría de acuerdo con un CVE con la opción de análisis de recuperación que sólo debería utilizarse para la recuperación manual al menos para el analizador de XML". • http://www.openwall.com/lists/oss-security/2016/11/05/3 http://www.openwall.com/lists/oss-security/2017/02/13/1 http://www.securityfocus.com/bid/96188 https://bugzilla.gnome.org/show_bug.cgi?id=778519 https://lists.debian.org/debian-lts-announce/2022/04/msg00004.html https://security.gentoo.org/glsa/201711-01 • CWE-476: NULL Pointer Dereference •
CVE-2016-9318 – libxml2: XML External Entity vulnerability
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 •
CVE-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 •
CVE-2016-5131 – libxml2: Use after free triggered by XPointer paths beginning with range-to
https://notcve.org/view.php?id=CVE-2016-5131
Use-after-free vulnerability in libxml2 through 2.9.4, as used in Google Chrome before 52.0.2743.82, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to the XPointer range-to function. Vulnerabilidad de uso después de liberación de memoria en libxml2 hasta la versión 2.9.4, como se utiliza en Google Chrome en versiones anteriores a 52.0.2743.82, permite a atacantes remotos provocar una denegación de servicio o posiblemente tener otro impacto no especificado a través de vectores relacionados con la función range-to XPointer. • http://googlechromereleases.blogspot.com/2016/07/stable-channel-update.html 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://lists.opensuse.org/opensuse-security-announce/2016-07/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2016-07/m • CWE-416: Use After Free •
