A header injection vulnerability in GNU Wget might allow remote attackers to inject arbitrary HTTP headers.
|Package||net-misc/wget on all architectures|
|Affected versions||< 1.19.1-r1|
|Unaffected versions||>= 1.19.1-r1|
GNU Wget is a free software package for retrieving files using HTTP, HTTPS and FTP, the most widely-used Internet protocols.
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.
A remote attacker could inject arbitrary HTTP headers in requests by tricking a user running GNU Wget into processing crafted URLs.
There is no known workaround at this time.
All GNU Wget users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/wget-1.19.1-r1"
