Description Srikanth Balasubramanian 2026-07-14 11:35:20 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.

Comment 1 Michal Ruprich 2026-07-16 07:48:05 UTC
This CVE is not applicable for wget2, only for the original GNU Wget. wget2 is a complete re-write and does not share any code with wget. Closing.
