NVD Description

Note: Versions mentioned in the description apply only to the upstream wget package and not the wget package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

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.
