Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200803-21
(Sarg: Remote execution of arbitrary code)

Sarg doesn't properly check its input for abnormal content when
processing Squid log files.

Impact :

A remote attacker using a vulnerable Squid as a proxy server or a
reverse-proxy server can inject arbitrary content into the 'User-Agent'
HTTP client header, that will be processed by sarg, which will lead to
the execution of arbitrary code, or JavaScript injection, allowing
Cross-Site Scripting attacks and the theft of credentials.

Workaround :

There is no known workaround at this time.
