(PHP: Multiple vulnerabilities)

    Several vulnerabilities were found in PHP by the Hardened-PHP Project
    and other researchers. These vulnerabilities include a heap-based
    buffer overflow in htmlentities() and htmlspecialchars() if called with
    UTF-8 parameters, and an off-by-one error in str_ireplace(). Other
    vulnerabilities were also found in the PHP4 branch, including possible
    overflows, stack corruptions and a format string vulnerability in the
    *print() functions on 64 bit systems.
  
Impact :

    Remote attackers might be able to exploit these issues in PHP
    applications making use of the affected functions, potentially
    resulting in the execution of arbitrary code, Denial of Service,
    execution of scripted contents in the context of the affected site,
    security bypass or information leak.
  
Workaround :

    There is no known workaround at this time."
