Descriptions

The xmlParseXMLDecl function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to obtain sensitive information via an (1) unterminated encoding value or (2) incomplete XML declaration in XML data, which triggers an out-of-bounds heap read.

La función xmlParseXMLDecl en parser.c en libxml2 en versiones anteriores a 2.9.3 permite a atacantes dependientes del contexto obtener información sensible a través de (1) un valor de codificiación indeterminado o (2) una declaración XML incompleta en datos XML, lo que desencadena una lectura de memoria dinámica fuera de rango.

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.
