CVE-2010-2531: Debian Linux

Medium severity, CVSS 4.3. EPSS: 5% chance of exploitation in the next 30 days.

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

• Debian Debian Linux: version 5.0 only; version 6.0 only
• PHP PHP: from 5.2.0, before 5.2.14 (fixed in 5.2.14); from 5.3.0, before 5.3.3 (fixed in 5.3.3)
