CVE-2018-13982: Debian Linux

High severity, CVSS 7.5. EPSS: 3.5% chance of exploitation in the next 30 days.

Smarty_Security::isTrustedResourceDir() in Smarty before 3.1.33 is prone to a path traversal vulnerability due to insufficient template code sanitization. This allows attackers controlling the executed template code to bypass the trusted directory security restriction and read arbitrary files.

Affected products

• Debian Debian Linux: version 9.0 only
• Smarty Smarty: before 3.1.33 (fixed in 3.1.33)
