FKIE_CVE-2010-2531
Vulnerability from fkie_nvd - Published: 2010-08-20 22:00 - Updated: 2026-06-16 23:20
Severity
Summary
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.
