The CVE-2025-XXXX vulnerability in `anon-vec` arises due to insufficient input validation in its public API functions: AnonVec::get_ref(), AnonVec::get_mut(), and AnonVec::remove_get(). These functions fail to properly validate indices, leading to potential out-of-bounds memory access. Attackers could exploit this flaw to read or modify unintended memory locations, though the impact is limited due to the crate’s unmaintained status. Since `anon-vec` was a learning project, no fixes are expected, but users should migrate to safer alternatives.
DailyCVE Form:
Platform: Rust crate
Version: All
Vulnerability: Memory unsafety
Severity: Low
Date: Jun 5, 2025
Prediction: No patch
What Undercode Say:
Analytics:
- Exploitability: Low (requires crafted input)
- Affected Users: Minimal (unmaintained crate)
- Mitigation: Replace crate
Exploit (PoC):
let mut vec = AnonVec::new(); vec.push(1); let _ = vec.get_ref(100); // OOB read
Protection:
1. Replace `anon-vec` with `std::Vec` or `smallvec`.
2. Audit code for `anon-vec` usage.
Commands:
cargo audit cargo update -p anon-vec --dry-run
Code Fix (Workaround):
// Manual bounds check
if index < vec.len() {
vec.get_ref(index);
}
Detection:
grep -r "anon-vec" ./src
Mitigation Steps:
1. Remove `anon-vec` from `Cargo.toml`.
2. Run `cargo build –verbose` to confirm.
Impact Analysis:
- No remote execution risk.
- Local memory corruption possible.
