Descriptions
The xmlSAX2TextNode function in SAX2.c in the push interface in the HTML parser in libxml2 before 2.9.3 allows context-dependent attackers to cause a denial of service (stack-based buffer over-read and application crash) or obtain sensitive information via crafted XML data.
La función xmlSAX2TextNode en SAX2.c en la interfaz push en el parser HTML en libxml2 en versiones anteriores a 2.9.3 permite a atacantes dependientes del contexto causar una denegación de servicio (sobre lectura de buffer basado en pila y caída de la aplicación) u obtener información sensible a través de datos XML manipulados.
A denial of service flaw was found in libxml2. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to leak potentially sensitive information.
Kostya Serebryany discovered that libxml2 incorrectly handled certain malformed documents. If a user or automated system were tricked into opening a specially crafted document, an attacker could possibly cause libxml2 to crash, resulting in a denial of service. CVE-2015-7497,CVE-2015-7498, CVE-2015-7499, Hugh Davenport discovered that libxml2 incorrectly handled certain malformed documents. If a user or automated system were tricked into opening a specially crafted document, an attacker could possibly cause libxml2 to crash, resulting in a denial of service. Various other issues were also addressed.
