<title>Wget: User-assisted file creation or overwrite</title>
<synopsis>Insecure usage of server provided filenames may allow the creation
or overwriting of local files.

<p>GNU Wget is a free software package for retrieving files using HTTP,
HTTPS and FTP, the most widely-used Internet protocols.
<p>It was discovered that Wget was unsafely trusting server-provided
filenames. This allowed attackers to overwrite or create files on the
user's system by sending a redirect from the expected URL to another URL
specifying the targeted file.
<impact type="normal">
<p>An unauthenticated remote attacker may be able to create or overwrite
local files by enticing the user to open an attacker controlled URL,
possibly leading to execution of arbitrary code.
<p>There is no known workaround at this time.</p>
<p>All Wget users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=net-misc/wget-1.12-r2"
<p>NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since September 19, 2010. It is likely that your system is
already no longer affected by this issue.
