Ubuntu 14.04 LTS : Wget vulnerability (USN-2393-1)

critical Nessus Plugin ID 78763

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2393-1 advisory.

 HD Moore discovered that Wget contained a path traversal vulnerability when downloading symlinks using FTP. A malicious remote FTP server or a man in the middle could use this issue to cause Wget to overwrite arbitrary files, possibly leading to arbitrary code execution.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected wget and / or wget-udeb packages.
