This memory leak could prevent traffic from being processed through the device, resulting in a denial of service (DoS) condition. The vulnerability is due to improper error handling when specific failures occur during IP fragment reassembly. An attacker could exploit this vulnerability by sending crafted, fragmented IP traffic to a targeted device. A successful exploit could allow the attacker to continuously consume memory on the affected device and eventually impact traffic, resulting in a DoS condition. The device could require a manual reboot to recover from the DoS condition. Note: This vulnerability applies to both IP Version 4 (IPv4) and IP Version 6 (IPv6) traffic."}, {"lang": "es", "value": "Una vulnerabilidad en la implementaci\u00f3n de manejo de fragmentos IP de Cisco Adaptive Security Appliance (ASA) Software y Cisco Firepower Threat Defense (FTD) Software, podr\u00eda permitir a un atacante remoto no autenticado causar una p\u00e9rdida de memoria en un dispositivo afectado. Esta p\u00e9rdida de memoria podr\u00eda impedir que el tr\u00e1fico sea procesado por medio del dispositivo, resultando en una condici\u00f3n de denegaci\u00f3n de servicio (DoS). La vulnerabilidad es debido al manejo inapropiado de errores cuando fallos espec\u00edficos ocurren durante el reensamblaje del fragmento IP. Un atacante podr\u00eda explotar esta vulnerabilidad mediante el env\u00edo de tr\u00e1fico IP fragmentado y dise\u00f1ado hacia un dispositivo objetivo. Una explotaci\u00f3n con \u00e9xito podr\u00eda permitir a un atacante consumir memoria continuamente en el dispositivo afectado y eventualmente impactar el tr\u00e1fico, resultando en una condici\u00f3n de DoS. El dispositivo podr\u00eda requerir un reinicio manual para recuperarse de la condici\u00f3n de DoS. Nota: Esta vulnerabilidad se aplica tanto al tr\u00e1fico IP versi\u00f3n 4 (IPv4) como al tr\u00e1fico IP versi\u00f3n 6 (IPv6)"}], "lastModified": "2024-11-21T05:30:54.193", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:cisco:firepower_threat_defense:6.6.0.1:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "20AE4051-FA3B-4F0B-BD3D-083A14269FF6"}, {"criteria": "cpe:2.3:o:cisco:adaptive_security_appliance_software:9.8.4.22:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "23CD5619-E534-4F40-998D-39DC19FA0451"}, {"criteria": "cpe:2.3:o:cisco:adaptive_security_appliance_software:9.8.4.25:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C5D0EB11-14B1-44B3-8D46-B9DD872F772C"}, {"criteria": "cpe:2.3:o:cisco:adaptive_security_appliance_software:9.12.4.2:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "7E23ACB0-DF8B-4672-A819-4DCD3104CE4A"}, {"criteria": "cpe:2.3:o:cisco:adaptive_security_appliance_software:9.12.4.3:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "714B961B-E808-4F9A-B6C3-7926BA813A81"}, {"criteria": "cpe:2.3:o:cisco:adaptive_security_appliance_software:9.13.1.12:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "40145CFB-CEE8-4ABA-A9C2-BA262B7A9AEC"}, {"criteria": "cpe:2.3:o:cisco:adaptive_security_appliance_software:9.14.1.15:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "6730194F-5069-40AB-AE66-871D3992560C"}], "operator": "OR"}]}], "sourceIdentifier": "ykramarz@cisco.com"}
