      "value": "GNU Wget through 1.25.0, fixed in commit 43d3ba9, contains an integer overflow vulnerability in the parse_content_range() function within src/http.c that allows server-controlled values to cause signed integer arithmetic to overflow. Attackers can supply malicious Content-Range header values to trigger undefined behavior and download desynchronization in the affected client."

      "value": "GNU Wget hasta 1.25.0, corregido en el commit 43d3ba9, contiene una vulnerabilidad de desbordamiento de entero en la función parse_content_range() dentro de src/http.c que permite que valores controlados por el servidor causen el desbordamiento de la aritmética de enteros con signo. Los atacantes pueden suministrar valores maliciosos en el encabezado Content-Range para desencadenar un comportamiento indefinido y desincronización de la descarga en el cliente afectado."
