Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200406-16
(Apache 1.3: Buffer overflow in mod_proxy)

A bug in the proxy_util.c file may lead to a remote buffer overflow. To
trigger the vulnerability an attacker would have to get mod_proxy to
connect to a malicous server which returns an invalid (negative)
Content-Length.

Impact :

An attacker could cause a Denial of Service as the Apache child handling
the request, which will die and under some circumstances execute arbitrary
code as the user running Apache, usually 'apache'.

Workaround :

There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version:
