Severity ?

6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Summary

Uncontrolled Recursion in rulex

Details

Impact

When parsing untrusted rulex expressions, the stack may overflow, possibly enabling a Denial of Service attack. This happens when parsing an expression with several hundred levels of nesting, causing the process to abort immediately.

This is a security concern for you, if - your service parses untrusted rulex expressions (expressions provided by an untrusted user), and - your service becomes unavailable when the process running rulex aborts due to a stack overflow.

Patches

The crash is fixed in version 0.4.3. Affected users are advised to update to this version.

Workarounds

None.
