PHP is a general purpose scripting language widely used in World Wide Web (WWW) pages and applications.
PHP's memory handling functions were found to contain an integer overflow vulnerability. Using a specially constructed request message, an attacker could possibly execute arbitrary code as the user apache on the server running PHP. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2006-4812 to this issue.
More information about this vulnerability can be found in the security advisory issued by RedHat Linux:
Avaya S87XX/S8500/S8300 is marked with a Risk Level of Low as PHP is installed in CM 2.x, but PHP is not utilized by anything on the system.
Avaya Intuity LX is marked with a Risk Level of Low as PHP is installed on the system but is not utilized by any applications.
Avaya CCS/SES is not affected as this vulnerability does not affect the versions of PHP installed on the various CCS/SES releases.
| Product: | Affected Version(s): | Risk Level: | Actions: |
|---|---|---|---|
| Avaya S87XX/S8500/S8300 | CM 2.2 versions prior to Load 126 | Low | Upgrade to CM 2.2 Load 127 or later in the CM 2.2 series or CM 3.1 or later in the CM 3.x series to remove PHP. |

Recommended Actions:
For all system products which use vulnerable
versions of PHP, Avaya recommends that customers restrict local and network
access to the server. This restriction should be enforced through the use of
physical security, firewalls, ACLs, VPNs, and other generally-accepted
networking practices until such time as an update becomes available and can
be installed.
Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.
In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendors guidance:
| Product: | Affected Version(s): | Risk Level: | Actions: |
|---|---|---|---|
| CVLAN | All | None | Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the CVLAN application. The CVLAN application does not require the software described in this advisory. |
| Avaya Integrated Management Suite(IMS) | All | None | Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the IMS application. The IMS application does not require the software described in this advisory. |
Recommended Actions:
Avaya recommends that customers follow
recommended actions supplied by RedHat Linux or remove the affected
package.
