Impact

This is a classic use‑after‑free bug (CWE-416) located in the SocketDescriptor::tcpReadHandler1 function of LIVE555 Streaming Media, specifically in RTPInterface.cpp. When an attacker sends a carefully crafted sequence of RTSP and HTTP requests, the server can be forced to consume invalid memory and crash. The result is a loss of service on the affected server.

Affected Systems

The vulnerability is present in LIVE555 Streaming Media version 2026.02.26. No other vendors or product families are listed.

Risk and Exploitability

The issue can be triggered remotely over the network through standard RTSP and HTTP traffic, resulting in a denial of service. The CVSS score is 6.5 and the EPSS score is < 1%. The vulnerability is not listed in the CISA KEV catalog, and the low exploitation probability implies that active attacks are unlikely but a vulnerable server accepting external requests remains at risk until a patch or mitigation is applied.

OpenCVE Recommended Actions

  • Upgrade to a recent release of LIVE555 that contains the fix for the use‑after‑free bug.
