- 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.
