X-REFERENCE: CVE Candidate - PHP (CAN-2002-0081) ,
Apache/mod_ssl(CAN-2002-0082)
PROBLEM SUMMARY:
Compaq was recently notified of two potential vulnerabilities
that impact Compaq's distributed Secure Web Server (CSWS) for
OpenVMS and TRU64 UNIX.
(SSRT0817) PHP
PHP (Hypertext Preprocessor scripting language). PHP does not
perform proper bounds checking on in functions related to
Form-based File Uploads in HTML to decode MIME encoded files.
This potential overflow vulnerability may allow arbitrary code
to be executed.
(SSRT0821) Apache/mod_ssl
Apache/mod_ssl session cache management routines use an unchecked
buffer that could potentially allow an overflow of a session cache
buffer. Thispotential vulnerability may allow arbitrary code to be
executed.
VERSIONS IMPACTED:
IMPACT:
CSWS (SSRT0817) PHP (SSRT0821)
Apache/mod_ssl
OpenVMS V7.1-2
or
later CSWS_PHP V1.0 CSWS V1.0-1,
CSWS V1.1-1,
CSWS V1.2
TRU64 UNIX V5.0A

Compaq Management Software Web Products
RESOLUTION:
Compaq has corrected both problems and created patches that are now
available for CSWS (Compaq Secure Web Server) for OpenVMS and TRU64
UNIX.
CSWS for OpenVMS V7.1-2 or later:
A Compaq Secure Web Server security update kit is available for
download at:

INSTALLED VERSION UPDATE KIT
CSWS_PHP 1.0 CSWS_PHP10_UPDATE V1.0
NOTE: (SSRT0817) PHP - For OpenVMS - if upgrading is not
possible or a patch cannot be applied immediately, the
potential PHP overflow vulnerability may be minimized by
adding the following line to MOD_PHP.CONF file:
PHP_FLAG file_uploads OFF
This will prevent using fileuploads, which may not be
an acceptable short-term solution.
(SSRT0821) Apache/mod_ssl

After completing the update, Compaq strongly recommends that you
perform an immediate backup of your system disk so that any
subsequent restore operations begin with updated software. Otherwise,
you must reapply the patch after a future restore operation. Also, if
at some future time you upgrade your system to a later patch version,
you may need to reapply the appropriate patch.
