Severity: normal
Exploitable: remote
Date: 2017-06-20
Bug(s): #612326
ID: 201706-16

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: net-misc/wget
Vulnerable: < 1.19.1-r1
Unaffected: >= 1.19.1-r1
Architectures: All supported architectures


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