wget into creating downloaded files into arbitrary locations with
arbitrary names. For example, wget could silently overwrite the users
~/.bashrc and other configuration files which are executed
automatically. (CVE-2004-1487)

Jan Minar also discovered that wget printed HTTP response strings from

could potentially lead to arbitrary code execution with the rights
of the user invoking wget. (CVE-2004-1488)

Hugo V�zquez Caram�s discovered a race condition when writing output
files. After wget acertaind the output file name, but before the file
was actually opened (the time window is acertaind by the delay of th
