Descriptions

In utils.c in zsh before 5.0.6, there is a buffer overflow when scanning very long directory paths for symbolic links.

En utils.c en zsh, en versiones anteriores a la 5.0.6, hay un desbordamiento de búfer al escanear rutas de directorio muy largas para detectar enlaces simbólicos.

A buffer overflow flaw was found in the zsh shell symbolic link resolver. A local, unprivileged user can create a specially crafted directory path which leads to a buffer overflow in the context of the user trying to do symbolic link resolution in the aforementioned path. An attacker could exploit this vulnerability to cause a denial of service condition on the target.
