CVE-2014-9748 is a high-severity vulnerability rated 8.1/10 on the CVSS scale. 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.. EPSS estimates a 2.47% chance of exploitation in the next 30 days.
