https://notcve.org/view.php?id=CVE-2019-13117
01 Jul 2019 — In numbers.c in libxslt 1.1.33, an xsl:number with certain format strings could lead to a uninitialized read in xsltNumberFormatInsertNumbers. This could allow an attacker to discern whether a byte on the stack contains the characters A, a, I, i, or 0, or any other character. En el archivo numbers.c en libxslt versión 1.1.33, un xsl:number con ciertas cadenas de formato conllevaría a una lectura no inicializada en la función xsltNumberFormatInsertNumbers. Esto podría permitir a un atacante discernir si un b... • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00062.html • CWE-908: Use of Uninitialized Resource •

CVE-2019-5815 – chromium-browser: Heap buffer overflow in Blink
https://notcve.org/view.php?id=CVE-2019-5815
07 May 2019 — 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. Nicolas Gregoire discovered that Libxslt incorrectly handled certain XML. An attacker could possibly use this issue to expose s... • https://bugs.chromium.org/p/chromium/issues/detail?id=930663 • CWE-787: Out-of-bounds Write CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •

CVE-2019-11068 – libxslt: xsltCheckRead and xsltCheckWrite routines security bypass by crafted URL
https://notcve.org/view.php?id=CVE-2019-11068
10 Apr 2019 — 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 ... • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00048.html • CWE-284: Improper Access Control •
