Descriptions

Composer before 2016-02-10 allows cache poisoning from other projects built on the same host. This results in attacker-controlled code entering a server-side build process. The issue occurs because of the way that dist packages are cached. The cache key is derived from the package name, the dist type, and certain other data from the package repository (which may simply be a commit hash, and thus can be found by an attacker). Versions through 1.0.0-alpha11 are affected, and 1.0.0 is unaffected.

Composer anterior al 10 de febrero de 2016 permite el envenenamiento de la caché de otros proyectos creados en el mismo host. Esto da como resultado que el código controlado por el atacante ingrese a un proceso de compilación del lado del servidor. El problema se debe a la forma en que se almacenan en caché los paquetes dist. La clave de caché se deriva del nombre del paquete, el tipo de dist y algunos otros datos del repositorio de paquetes (que pueden ser simplemente un hash de confirmación y, por lo tanto, un atacante puede encontrarlos). Las versiones hasta 1.0.0-alpha11 se ven afectadas y la 1.0.0 no.
