POTENTIAL SECURITY IMPACT:   	

Remote Denial of Service (DoS) and execurtion of arbitrary code.
SOURCE:

VULNERABILITY SUMMARY:
Two security vulnerabilities have been reported in Apache HTTP server (http://httpd.apache.org/) versions prior to Apache 1.3.33 that may allow
a Denial of Service (DoS) attack and execution of arbitrarty code.
REFERENCES:   	

CAN-2004-0492, CAN-2004-0940
SUPPORTED SOFTWARE VERSIONS*:  ONLY impacted versions are listed.
HP-UX B.11.04 with VirtualVault 4.7, Virtualvault 4.6, or
VirtualVault 4.5, and HP Webproxy A.02.10 and A.02.00 only.
BACKGROUND:
The Apache group, while announcing the release Apache HTTP
Server version 1.3.33, said that the following security defects
had been addressed.

1. Heap-based buffer overflow in mod_proxy in Apache 1.3.25
   to 1.3.31 allows remote attackers to cause a denial of
   service (process crash) and possibly execute arbitrary
   code via a negative Content-Length HTTP header field, which
   causes a large amount of data to be copied.

2. Buffer overflow in mod_include for Apache 1.3.x to 1.3.32
   allows local users who can create SSI documents to execute
   arbitrary code as the apache user via SSI (XSSI) documents
   that trigger a length calculation error.
