Descriptions

Versions of add-apt-repository before 0.98.9.2, 0.96.24.32.14, 0.96.20.10, and 0.92.37.8ubuntu0.1~esm1, printed a PPA (personal package archive) description to the terminal as-is, which allowed PPA owners to provide ANSI terminal escapes to modify terminal contents in unexpected ways.

Las versiones de add-apt-repository anteriores a 0.98.9.2, 0.96.24.32.14, 0.96.20.10 y 0.92.37.8ubuntu0.1~esm1, imprimieron una descripción PPA (personal package archive) en el terminal as-is, lo que permitió a los propietarios de PPA proporcionar escapes del terminal ANSI para modificar el contenido del terminal de formas no previstas
