      "value": "rAthena is an open-source cross-platform massively multiplayer online role playing game (MMORPG) server. Versions prior to commit 2f5248b have a heap-based buffer overflow in the login server, remote attacker to overwrite adjacent session fields by sending a crafted `CA_SSO_LOGIN_REQ` with an oversized token length. This leads to immediate denial of service (crash) and it is possible to achieve remote code execution via heap corruption. Commit 2f5248b fixes the issue."

      "value": "rAthena es un servidor de juego de rol multijugador masivo en línea (MMORPG) de código abierto y multiplataforma. Las versiones anteriores al commit 2f5248b tienen un desbordamiento de búfer basado en montículo en el servidor de inicio de sesión, lo que permite a un atacante remoto sobrescribir campos de sesión adyacentes enviando un 'CA_SSO_LOGIN_REQ' manipulado con una longitud de token excesiva. Esto conduce a una denegación de servicio inmediata (caída) y es posible lograr la ejecución remota de código mediante corrupción de montículo. El commit 2f5248b corrige el problema."
