CVE-2011-1464
Description
From CVE.org
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.
Statement
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.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
