CVE-2026-58470

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.

Summary		(es) 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.
