"The Drupal development team reports : Inconsistent name for term
access query (Less critical - Drupal 7 and Drupal 8) Drupal provides a
mechanism to alter database SELECT queries before they are executed.
Contributed and custom modules may use this mechanism to restrict
access to certain entities by implementing hook_query_alter() or
hook_query_TAG_alter() in order to add additional conditions. Queries
can be distinguished by means of query tags. As the documentation on
EntityFieldQuery::addTag() suggests, access-tags on entity queries
normally follow the form ENTITY_TYPE_access (e.g. node_access).
However, the taxonomy module's access query tag predated this system
and used term_access as the query tag instead of taxonomy_term_access.

As a result, before this security release modules wishing to restrict
access to taxonomy terms may have implemented an unsupported tag, or
needed to look for both tags (term_access and taxonomy_term_access) in
order to be compatible with queries generated both by Drupal core as
well as those generated by contributed modules like Entity Reference.
Otherwise information on taxonomy terms might have been disclosed to
unprivileged users.

Incorrect cache context on password reset page (Less critical - Drupal
8) The user password reset form does not specify a proper cache
context, which can lead to cache poisoning and unwanted content on the
page. Confirmation forms allow external URLs to be injected
(Moderately critical - Drupal 7) Under certain circumstances,
malicious users could construct a URL to a confirmation form that
would trick users into being redirected to a 3rd party website after
interacting with the form, thereby exposing the users to potential
social engineering attacks. Denial of service via transliterate
mechanism (Moderately critical - Drupal 8) A specially crafted URL can
cause a denial of service via the transliterate mechanism."

vulnerabilities :

  - An information disclosure vulnerability exists in the
    taxonomy module when using access query tags that are
    inconsistent with the standard system used by Drupal
    Core. An unauthenticated, remote attacker can exploit
    this to disclose sensitive information regarding
    taxonomy terms. (CVE-2016-9449)

  - A flaw exists in the password reset form due to a
    failure to properly specify a cache context. An
    unauthenticated, remote attacker can exploit this to
    poison the cache, by adding, for example, unwanted
    content to the page. Note that this issue only
    affects version 8.x. (CVE-2016-9450)

  - A cross-site redirection vulnerability exists in the
    confirmation form due to improper validation of input
    before returning it to users. An unauthenticated, remote
    attacker can exploit this, via a specially crafted link,
    to redirect the user to a website of the attacker's
    choosing. Note that this issue only affects version
    7.x. (CVE-2016-9451)

  - A denial of service vulnerability exists in the
    transliterate mechanism when handling specially crafted
    URLs. An unauthenticated, remote attacker can exploit
    this to cause a crash. Note that this issue only affects
    version 8.x. (CVE-2016-9452)

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.");
