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.

Affected products and versions

  • PHP — From 5.2.0 (including) to 5.2.14 (excluding)
  • PHP — From 5.3.0 (including) to 5.3.3 (excluding)
