Summary

Stack overflow during recursive expression parsing

Details

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.

The flaw was corrected in commits 60aa2dc03a by adding a check to recursion depth.

CVE-2022-31099 (GCVE-0-2022-31099)

Vulnerability from cvelistv5 – Published: 2022-06-27 22:10 – Updated: 2025-04-23 18:06

Title

Uncontrolled Recursion in rulex

Summary

rulex is a new, portable, regular expression language. 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. The crash is fixed in version **0.4.3**. Affected users are advised to update to this version. There are no known workarounds for this issue.

Severity ?
