Ubuntu 12.04 LTS / 14.04 LTS / 15.10 / 16.04 LTS : wget vulnerability (USN-3012-1)

Medium Nessus Plugin ID 91728


The remote Ubuntu host is missing a security-related patch.


Dawid Golunski discovered that Wget incorrectly handled filenames when being redirected from an HTTP to an FTP URL. A malicious server could possibly use this issue to overwrite local files.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected wget package.
