Test Kennung:1.3.6.1.4.1.25623.1.0.120720
Kategorie:Amazon Linux Local Security Checks
Titel:Amazon Linux: Security Advisory (ALAS-2016-731)
Zusammenfassung:The remote host is missing an update for the 'golang' package(s) announced via the ALAS-2016-731 advisory.
Beschreibung:Summary:
The remote host is missing an update for the 'golang' package(s) announced via the ALAS-2016-731 advisory.

Vulnerability Insight:
An input-validation flaw was discovered in the Go programming language built in CGI implementation, which set the environment variable 'HTTP_PROXY' using the incoming 'Proxy' HTTP-request header. The environment variable 'HTTP_PROXY' is used by numerous web clients, including Go's net/http package, to specify a proxy server to use for HTTP and, in some cases, HTTPS requests. This meant that when a CGI-based web application ran, an attacker could specify a proxy server which the application then used for subsequent outgoing requests, allowing a man-in-the-middle attack.

Affected Software/OS:
'golang' package(s) on Amazon Linux.

Solution:
Please install the updated package(s).
