SSRT5902 rev.0 Apache 1.3 on VirtualVault potential remote Denial
of Service (DoS) and execution of arbitrary code
NOTICE:
There are no restrictions for distribution of this Security
Bulletin provided that it remains complete and intact.
The information in this Security Bulletin should be acted upon
as soon as possible.
INITIAL RELEASE:
27 January 2005
POTENTIAL SECURITY IMPACT:
Remote Denial of Service (DoS) and execurtion of arbitrary code.
SOURCE:
Hewlett-Packard Company
HP Software Security Response Team
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.
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0492
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.
