| Package | Affected versions | Patched versions |
|---|---|---|
| libuv | < 1.7.4 | 1.7.4 |
| node.js | ≥ 0.10.0, < 0.10.46≥ 0.12.0, < 0.12.15 | 0.10.460.12.15 |
The uv_rwlock_t fallback implementation for Windows XP and Server 2003 in libuv before 1.7.4 does not properly prevent threads from releasing the locks of other threads, which allows attackers to cause a denial of service (deadlock) or possibly have unspecified other impact by leveraging a race condition.
