CVE-2013-1051

apt v0.8.16, v0.9.7 y posiblemente otras versiones no trata correctamente los archivos InRelease, lo que permite man-in-the-middle atacantes para modificar los paquetes antes de la instalación a través de vectores desconocidos, posiblemente relacionadas con la comprobación de la integridad y el uso de terceros repositorios del partido.

Ansgar Burchardt discovered that APT incorrectly handled repositories that use InRelease files. The default Ubuntu repositories do not use InRelease files, so this issue only affected third-party repositories. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could potentially be used to install altered packages. This update corrects the issue by disabling InRelease file support completely. Various other issues were also addressed.
