Apache 1.3: Buffer overflow in mod_proxy

Detailed Explanation for this Vulnerability Assessment
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 a possible hacker would have to get mod_proxy to
connect to a malicous server which returns an invalid (negative)

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:
