QID 995321: PHP (Composer) Security Update for composer/composer (GHSA-725m-w832-q973)

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.

Successful exploitation of this vulnerability could lead to a security breach or could affect integrity, availability, and confidentiality.
