    CVE-2011-10020 (GCVE-0-2011-10020)

    Vulnerability from cvelistv5 – Published: 2025-08-20 15:35 – Updated: 2026-05-15 11:13 Unsupported When Assigned
    VLAI
    Title
    Kaillera 0.86 Server DoS via Malformed UDP Packet
    Summary
    Kaillera Server version 0.86 is vulnerable to a denial-of-service condition triggered by sending a malformed UDP packet after the initial handshake. Once a client sends a valid HELLO0.83 packet and receives a response, any subsequent malformed packet causes the server to crash and become unresponsive. This flaw stems from improper input validation in the server’s UDP packet handler, allowing unauthenticated remote attackers to disrupt service availability.
