689365: CVE-2011-1464 php: Crash by retrieving string value of a variable, when high precision used

The MITRE CVE dictionary describes this issue as:

Buffer overflow in the strval function in PHP before 5.3.6, when the precision configuration option has a large value, might allow context-dependent attackers to cause a denial of service (application crash) via a small numerical value in the argument.

Red Hat does not consider this flaw to be a security issue. It is improbable that a script would accept untrusted user input or unvalidated script input data to the strval() function. Input passed to the functions is therefore under the full control of the script author and no trust boundary is crossed. As well, an administrator would have to excessively increase the precision settings in order to trigger this flaw.
