PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. PHP's fileinfo module provides functions used to identify a particular file according to the type of data contained by the file.
It was found that the fix for CVE-2012-1571 was incomplete; the File Information (fileinfo) extension did not correctly parse certain Composite Document Format (CDF) files. A remote attacker could use this flaw to crash a PHP application using fileinfo via a specially crafted CDF file. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2014-3587 to this issue.
A NULL pointer dereference flaw was found in the gdImageCreateFromXpm() function of PHP's gd extension. A remote attacker could use this flaw to crash a PHP application using gd via a specially crafted X PixMap (XPM) file. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2014-2497 to this issue.
Multiple buffer over-read flaws were found in the php_parserr() function of PHP. A malicious DNS server or a man-in-the-middle attacker could possibly use this flaw to execute arbitrary code as the PHP interpreter if a PHP application used the dns_get_record() function to perform a DNS query. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2014-3597 to this issue.
Two use-after-free flaws were found in the way PHP handled certain Standard PHP Library (SPL) Iterators and ArrayIterators. A malicious script author could possibly use either of these flaws to disclose certain portions of server memory. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2014-4670 and CVE-2014-4698 to these issues.
Note: these issues impact php53 packages on RHEL5 and php packages on RHEL6.

Recommended Actions for System Products:
Avaya strongly recommends following networking and
security best practices by implementing firewalls, ACLs,
physical security or other appropriate access restrictions.
Though Avaya believes such restrictions should always be in
place, risk to Avaya products and the surrounding network
from this potential vulnerability may be mitigated by
ensuring these practices are implemented until such time as
an Avaya provided product update or the recommended Avaya
action is applied.
Further restrictions as deemed necessary based on the
customer's security policies may be required during this
interim period, but the System Product operating system or
application should not be modified unless the change is
approved by Avaya. Making changes that are not approved may
void the Avaya product service contract.
When determining risk, Avaya takes into account many factors as outlined by Avaya's Security Vulnerability Classification Policy. The following table describes factors that mitigate the risk of specific vulnerabilities for affected Avaya products:
| Vulnerability | Mitigating Factors |
|---|---|
|
CVE-2014-2497 CVE-2014-3587 CVE-2014-3597 CVE-2014-4670 CVE-2014-4698 |
These are a Low risk for all listed products because the vulnerable functions are not used by default. |
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 vendor's guidance.
