Description Andrej Nemec 2016-04-18 14:41:23 UTC 
A possible vulnerability was found in wget. The vulnerability surfaces when wget is used to download a single file with recursive option (-r / -m) and an access list ( -A ), wget only applies the list at the end of the download process.

Although the file get successfully deleted in the end, this creates a race condition situation as an attacker who has control over the URL, could slow down the download process so that he had a chance to make use of the malicious file before it gets deleted.
