Descriptions

In Git before 2.13.7, 2.14.x before 2.14.4, 2.15.x before 2.15.2, 2.16.x before 2.16.4, and 2.17.x before 2.17.1, code to sanity-check pathnames on NTFS can result in reading out-of-bounds memory.

En Git, en versiones anteriores a la 2.13.7, versiones 2.14.x anteriores a la 2.14.4, versiones 2.15.x anteriores a la 2.15.2, versiones 2.16.x anteriores a la 2.16.4 y versiones 2.17.x anteriores a la 2.17.1, el código para comprobar el saneamiento de los nombres de ruta en NTFS puede resultar en la lectura de memoria fuera de límites.

Git is a distributed revision control system with a decentralized architecture. As opposed to centralized version control systems with a client-server model, Git ensures that each working copy of a Git repository is an exact copy with complete revision history. This not only allows the user to work on and contribute to projects without the need to have permission to push the changes to their official repositories, but also makes it possible for the user to work with no network connection. Issues addressed include a code execution vulnerability.
