Summary
Live555 through 1.08 does not handle socket connections properly. A huge number of incoming socket connections in a short time invokes the error-handling module, in which a heap-based buffer overflow happens. An attacker can leverage this to launch a DoS attack.
Exploit prediction
1.37% chance of exploitation in the next 30 days, higher than 72% of all scored CVEs (FIRST EPSS, 2026-11-08).
