GLSA-201110-10 : Wget: User-assisted file creation or overwrite

This script is Copyright (C) 2011-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-201110-10
(Wget: User-assisted file creation or overwrite)

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 :

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.

Workaround :

There is no known workaround at this time.

Solution :

All Wget users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=net-misc/wget-1.12-r2'
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.

Risk factor :

Medium / CVSS Base Score : 6.8
