CVE-2010-2531 Information
Share on:Description
The var_export function in PHP 5.2 before 5.2.14 and 5.3 before 5.3.3 flushes the output buffer to the user when certain fatal errors occur even if display_errors is off which allows remote attackers to obtain sensitive information by causing the application to exceed limits for memory execution time or recursion.
