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

Hewlett-Packard Company
HP Software Security Response Team

Two security vulnerabilities have been reported in Apache HTTP
server ( /) versions prior to Apache 1.3.33
that may allow a Denial of Service (DoS) attack and execution of
arbitrarty code.
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.

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.


Note: To determine if a system has an affected version,
      search the output of "swlist -a revision -l fileset"
      for an affected fileset.  Then determine if the
      recommended patch or update is installed.
