Descriptions

zsh before 5.0.7 allows evaluation of the initial values of integer variables imported from the environment (instead of treating them as literal numbers). That could allow local privilege escalation, under some specific and atypical conditions where zsh is being invoked in privilege-elevation contexts when the environment has not been properly sanitized, such as when zsh is invoked by sudo on systems where "env_reset" has been disabled.

zsh, en versiones anteriores a la 5.0.7, permite la evaluación de los valores- iniciales de las variables de enteros importadas del entorno (en lugar de tratarlas como números literales). Esto podría permitir el escalado de privilegios local, bajo ciertas condiciones específicas y atípicas, cuando zsh se está invocando en contextos de elevación de privilegios en los que el entorno no se ha saneado correctamente, como cuando zsh se invoca en sistemas en los que se ha deshabilitado "env_reset".

It was discovered that Zsh incorrectly handled certain environment variables. An attacker could possibly use this issue to gain privileged access to the system. This issue only affected Ubuntu 14.04 LTS. It was discovered that Zsh incorrectly handled certain inputs. An attacker could possibly use this to execute arbitrary code. This issue only affected Ubuntu 14.04 LTS. Various other issues were also addressed.
