A local cross-user code execution vulnerability exists in GNU wget (Windows builds from eternallybored.org) due to a hardcoded configuration file path (C:\msys64) that is writable by unprivileged users, allowing for arbitrary code execution via the useaskpass directive, potentially allowing local privilege escalation.

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.
