Descriptions
In Mercurial before 4.4.1, it is possible that a specially malformed repository can cause Git subrepositories to run arbitrary code in the form of a .git/hooks/post-update script checked into the repository. Typical use of Mercurial prevents construction of such repositories, but they can be created programmatically.
En Mercurial, en versiones anteriores a la 4.4.1, es posible que un repositorio especialmente mal formado provoque que los subrepositorios Git ejecuten código arbitrario en la forma de un script .git/hooks/post-update verificado en el repositorio. El uso habitual de Mercurial evita la construcción de tales repositorios, pero pueden crearse programáticamente.
