CVE-2025-4637Network attack vector

Unauthenticated application crash

Published May 14, 2025 · Updated May 15, 2025

Divide-by-zero in Davis King dlib before 19.24.7 allows remote attackers to crash applications that process a crafted file. Published CVE materials do not identify the affected file parser, function, or zero-valued divisor. Exploitation requires an application to pass attacker-controlled file content to the vulnerable dlib path; the reported consequence is an availability-only process crash.
