GLSA-201706-16 : GNU Wget: Header injection
Medium Nessus Plugin ID 100942
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201706-16 (GNU Wget: Header injection)
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.
SolutionAll GNU Wget users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/wget-1.19.1-r1'
