Updated drupal packages fix security vulnerabilities:
An information disclosure vulnerability was discovered in Drupal
before 7.27. When pages are cached for anonymous users, form state
may leak between anonymous users. Sensitive or private information
recorded for one anonymous user could thus be disclosed to other
users interacting with the same form at the same time (CVE-2014-2983).
Multiple security issues in Drupal before 7.29, including a denial
of service issue, an access bypass issue in the File module, and
multiple cross-site scripting issues (CVE-2014-5019, CVE-2014-5020,
CVE-2014-5021, CVE-2014-5022).
A denial of service issue exists in Drupal before 7.31, due to XML
entity expansion in a publicly accessible XML-RPC endpoint.
An SQL Injection issue exists in Drupal before 7.32 due to the way
the Drupal core handles prepared statements. A malicious user can
inject arbitrary SQL queries, and thereby completely control the
Drupal site. This vulnerability can be exploited by remote attackers
without any kind of authentication required (CVE-2014-3704).
Aaron Averill discovered that a specially crafted request can give a
user access to another user’s session, allowing an attacker to hijack
a random session (CVE-2014-9015).
Michael Cullum, Javier Nieto and Andres Rojas Guerrero discovered
that the password hashing API allows an attacker to send specially
crafted requests resulting in CPU and memory exhaustion. This may lead
to the site becoming unavailable or unresponsive (denial of service)
(CVE-2014-9016). anonymous users (CVE-2014-9016).
Password reset URLs can be forged under certain circumstances, allowing
an attacker to gain access to another user’s account without knowing
the account’s password (CVE-2015-2559).
Under certain circumstances, malicious users can construct a URL
that will trick users into being redirected to a 3rd party website,
thereby exposing the users to potential social engineering attacks. In
addition, several URL-related API functions in Drupal 6 and 7 can be
tricked into passing through external URLs when not intending to,
potentially leading to additional open redirect vulnerabilities
(CVE-2015-2749, CVE-2015-2750).
The drupal package has been updated to version 7.35 to fix this
issue and other bugs. See the upstream advisory and release notes
for more details.
