Synopsis
========
A header injection vulnerability in GNU Wget might allow remote
attackers to inject arbitrary HTTP headers.

Background
==========
GNU Wget is a free software package for retrieving files using HTTP,
HTTPS and FTP, the most widely-used Internet protocols.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-misc/wget < 1.19.1-r1 >= 1.19.1-r1

Description
===========
It was discovered that there was a header injection vulnerability in
GNU Wget which allowed remote attackers to inject arbitrary HTTP
headers via CRLF sequences in the host subcomponent of a URL.

Impact
======
A remote attacker could inject arbitrary HTTP headers in requests by
tricking a user running GNU Wget into processing crafted URLs.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All GNU Wget users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/wget-1.19.1-r1"

References
