The vulnerability (RUSTSEC-2022-0030) was discovered in the rulex Rust package, affecting versions 0.4.2 and below. The issue was disclosed on June 21, 2022, and involves an uncontrolled recursion vulnerability that could lead to stack overflow conditions (GitHub Advisory).
Technical details
The vulnerability is classified as CWE-674 (Uncontrolled Recursion) and was assigned CVE-2022-31099. The issue manifests when parsing rulex expressions with several hundred levels of nesting, which can trigger a stack overflow condition, causing the process to terminate immediately (GitHub Advisory).
Impact
When exploited, this vulnerability can cause a Denial of Service (DoS) condition by forcing the process running rulex to abort due to stack overflow. This is particularly concerning for services that parse untrusted rulex expressions provided by users (GitHub Advisory).
