Descriptions

zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow in inflate in inflate.c via a large gzip header extra field. NOTE: only applications that call inflateGetHeader are affected. Some common applications bundle the affected zlib source code but may be unable to call inflateGetHeader (e.g., see the nodejs/node reference).

zlib versiones hasta 1.2.12, presenta una lectura excesiva de búfer en la región heap de la memoria o desbordamiento de búfer en el archivo inflate.c por medio de un campo extra del encabezado gzip. NOTA: sólo están afectadas las aplicaciones que llaman a inflateGetHeader. Algunas aplicaciones comunes agrupan el código fuente de zlib afectado pero pueden ser incapaces de llamar a inflateGetHeader (por ejemplo, véase la referencia nodejs/node)

A security vulnerability was found in zlib. The flaw triggered a heap-based buffer in inflate in the inflate.c function via a large gzip header extra field. This flaw is only applicable in the call inflateGetHeader.
