Descriptions

Hardlink before 0.1.2 suffer from multiple stack-based buffer overflow flaws because of the way directory trees with deeply nested directories are processed. A remote attacker could provide a specially-crafted directory tree, and trick the local user into consolidating it, leading to hardlink executable crash, or, potentially arbitrary code execution with the privileges of the user running the hardlink executable.

Hardlink versiones anteriores a 0.1.2, sufre de múltiples fallos de desbordamiento de búfer en la región stack de la memoria debido a la manera en que son procesados los árboles de directorios con directorios profundamente anidados. Un atacante remoto podría proveer un árbol de directorios especialmente diseñado y engañar al usuario local para consolidarlo, conllevando a un bloqueo del ejecutable de hardlink o una ejecución de código potencialmente arbitraria con los privilegios del usuario que ejecuta el ejecutable de hardlink.
