Descriptions
Memory leak in the poolGrow function in expat/lib/xmlparse.c in expat before 2.1.0 allows context-dependent attackers to cause a denial of service (memory consumption) via a large number of crafted XML files that cause improperly-handled reallocation failures when expanding entities.
Múltiples fugas de memoria en la función poolGrow en expat/lib/xmlparse.c en expat anteriores a v2.1.0 podría permitir a atacantes remotos provocar una denegación de servicio (consumo de memoria) a través de un número largo de ficheros XML manipulados que provocan fallos en la relocalización cuando se expanden las entidades.
A memory leak flaw was found in Expat. If an XML file processed by an application linked against Expat triggered a memory re-allocation failure, Expat failed to free the previously allocated memory. This could cause the application to exit unexpectedly or crash when all available memory is exhausted.
