Descriptions

Directory traversal vulnerability in the BusyBox implementation of tar before 1.22.0 v5 allows remote attackers to point to files outside the current working directory via a symlink.

Una vulnerabilidad de salto de directorio en la implementación de tar en BusyBox en versiones anteriores a 1.22.0 v5 permite que atacantes remotos apunten a archivos situados fuera del actual directorio de trabajo a través de un symlink.

Tyler Hicks discovered that BusyBox incorrectly handled symlinks inside tar archives. If a user or automated system were tricked into processing a specially crafted tar archive, a remote attacker could overwrite arbitrary files outside of the current directory. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. Mathias Krause discovered that BusyBox incorrectly handled kernel module loading restrictions. A local attacker could possibly use this issue to bypass intended restrictions. This issue only affected Ubuntu 14.04 LTS. Various other issues were also addressed.
