CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Description
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.
Exploitation
Not listed in the CISA Known Exploited Vulnerabilities catalogue as of 2026.09.04. That is an absence of confirmed public exploitation, not evidence that exploitation has not occurred. EPSS models a 1.3% probability of exploitation activity in the next 30 days.
