Type confusion in xsltNumberFormatGetMultipleLevel prior to libxslt 1.1.33 could allow attackers to potentially exploit heap corruption via crafted XML data. Una confusión de tipo en la función xsltNumberFormatGetMultipleLevel versiones anteriores a libxslt versión 1.1.33, podría permitir a atacantes explotar potencialmente la corrupción de la pila por medio de datos XML diseñados. • https://bugs.chromium.org/p/chromium/issues/detail?id=930663 https://gitlab.gnome.org/GNOME/libxslt/commit/08b62c25871b38d5d573515ca8a065b4b8f64f6b https://lists.debian.org/debian-lts-announce/2022/09/msg00010.html https://access.redhat.com/security/cve/CVE-2019-5815 https://bugzilla.redhat.com/show_bug.cgi?id=1702905 • CWE-787: Out-of-bounds Write CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •

libxslt through 1.1.33 allows bypass of a protection mechanism because callers of xsltCheckRead and xsltCheckWrite permit access even upon receiving a -1 error code. xsltCheckRead can return -1 for a crafted URL that is not actually invalid and is subsequently loaded. libxslt hasta la versión 1.1.33 permite omitir los mecanismos de protección debido a que los callers xsltCheckRead y xsltCheckWrite permiten acceso incluso después de recibir el código de error -1. xsltCheckRead puede devolver -1 para una URL creada que no es realmente inválida y que se carga posteriormente. • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00048.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00053.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00001.html http://www.openwall.com/lists/oss-security/2019/04/22/1 http://www.openwall.com/lists/oss-security/2019/04/23/5 https • CWE-284: Improper Access Control •

In libxslt 1.1.29 and earlier, the EXSLT math.random function was not initialized with a random seed during startup, which could cause usage of this function to produce predictable outputs. En libxslt 1.1.29 y anteriores, la función EXSLT math.random no se inició con una seed aleatoria durante el arranque, lo que podría hacer que el uso de esta función produzca salidas predecibles. • https://bugzilla.gnome.org/show_bug.cgi?id=758400 https://bugzilla.suse.com/show_bug.cgi?id=934119 • CWE-330: Use of Insufficiently Random Values •

The xsltAddTextString function in transform.c in libxslt 1.1.29, as used in Blink in Google Chrome prior to 57.0.2987.98 for Mac, Windows, and Linux and 57.0.2987.108 for Android, lacked a check for integer overflow during a size calculation, which allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page. La función xsltAddTextString en transform.c en libxslt 1.1.29, tal como se utiliza en Blink en Google Chrome anteriores a 57.0.2987.98 para Mac, Windows y Linux y 57.0.2987.108 para Android, carecía de una comprobación de desbordamiento de entero durante un cálculo de tamaño, lo que permite a un atacante remoto realizar una escritura de memoria fuera de límites a través de una página HTML diseñada. • http://rhn.redhat.com/errata/RHSA-2017-0499.html http://www.debian.org/security/2017/dsa-3810 http://www.securityfocus.com/bid/96767 http://www.securitytracker.com/id/1038157 https://chromereleases.googleblog.com/2017/03/stable-channel-update-for-desktop.html https://crbug.com/676623 https://git.gnome.org/browse/libxslt/commit/?id=08ab2774b870de1c7b5a48693df75e8154addae5 https://access.redhat.com/security/cve/CVE-2017-5029 https://bugzilla.redhat.com/show_bug.cgi?id=1431033 • CWE-787: Out-of-bounds Write •
