Use after free in libxml2 before 2.9.5, as used in Google Chrome prior to 63.0.3239.84 and other products, allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. Uso de memoria previamente liberada en libxml2 en versiones anteriores a la 2.9.5, tal y como se emplea en Google Chrome en versiones anteriores a la 63.0.3239.84 y otros productos, permitía que un atacante remoto pudiese explotar una corrupción de memoria dinámica (heap) mediante una página HTML manipulada. A use-after-free flaw was found in the libxml2 library. An attacker could use this flaw to cause an application linked against libxml2 to crash when parsing a specially crafted XML file. • http://www.securitytracker.com/id/1040348 https://access.redhat.com/errata/RHSA-2017:3401 https://access.redhat.com/errata/RHSA-2018:0287 https://bugzilla.gnome.org/show_bug.cgi?id=783160 https://chromereleases.googleblog.com/2017/12/stable-channel-update-for-desktop.html https://crbug.com/727039 https://lists.debian.org/debian-lts-announce/2017/12/msg00014.html https://security.gentoo.org/glsa/201801-03 https://www.debian.org/security/2018/dsa-4086 https://access.redhat. • CWE-416: Use After Free •

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 •
