- Summary
- GNU Wget 1.25.0 Heap Buffer Underread via Metalink URL Parsing
- Details
-
GNU Wget through 1.25.0, fixed in commit 37a40fc, contains a heap buffer underread vulnerability in the cleanmetalinkstring() 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.
