NVD Description

Note: Versions mentioned in the description apply only to the upstream wget package and not the wget package as distributed by Ubuntu. See How to fix? for Ubuntu:26.04 relevant fixed versions and status.

GNU Wget through 1.25.0, fixed in commit 37a40fc, contains a heap buffer underread vulnerability in the clean_metalink_string() function within src/metalink.c that allows a malicious server to trigger memory corruption by serving a Metalink document containing a whitespace-only URL. Attackers can cause the function to decrement a pointer past the start of the buffer when processing an all-whitespace Metalink URL, potentially leading to abnormal program behavior.
