Descriptions

AIDE before 0.17.4 allows local users to obtain root privileges via crafted file metadata (such as XFS extended attributes or tmpfs ACLs), because of a heap-based buffer overflow.

AIDE versiones anteriores a 0.17.4, permite a usuarios locales obtener privilegios de root por medio de metadatos de archivo diseñados (como atributos extendidos de XFS o ACLs de tmpfs), debido a un desbordamiento de búfer en la región heap de la memoria

A heap-based buffer overflow vulnerability in the base64 functions of AIDE, an advanced intrusion detection system. An attacker could crash the program and possibly execute arbitrary code through large (<16k) extended file attributes or ACL.
