      "value": "wb2osz/direwolf (Dire Wolf) versions up to and including 1.8.1, prior to commit 3658a87, contain a reachable assertion vulnerability in the APRS MIC-E decoder function aprs_mic_e() located in src/decode_aprs.c. When processing a specially crafted AX.25 frame containing a MIC-E message with an empty or truncated comment field, the application triggers an unhandled assertion checking for a non-empty comment. This assertion failure causes immediate process termination, allowing a remote, unauthenticated attacker to cause a denial of service by sending malformed APRS traffic."

      "value": "wb2osz/direwolf (Dire Wolf) versiones hasta e incluyendo 1.8, versiones anteriores al commit 3658a87, contienen una vulnerabilidad de aserción alcanzable en la función decodificadora APRS MIC-E aprs_mic_e() ubicada en src/decode_aprs.c. Al procesar una trama AX.25 especialmente diseñada que contiene un mensaje MIC-E con un campo de comentario vacío o truncado, la aplicación activa una aserción no manejada que verifica un comentario no vacío. Este fallo de aserción provoca la terminación inmediata del proceso, lo que permite a un atacante remoto no autenticado causar una denegación de servicio al enviar tráfico APRS malformado."
