Package : ruby-actionpack-3.2

Version : 3.2.6-6+deb7u3

CVE ID : CVE-2015-7576 CVE-2016-0751 CVE-2016-0752 CVE-2016-2097

CVE-2016-2098 CVE-2016-6316

 

Multiple vulnerabilities have been discovered in ruby-actionpack-3.2, a

web-flow and rendering framework and part of Rails:

 

CVE-2015-7576

 

A flaw was found in the way the Action Controller component compared

user names and passwords when performing HTTP basic

authentication. Time taken to compare strings could differ depending

on input, possibly allowing a remote attacker to determine valid user

names and passwords using a timing attack.

 

CVE-2016-0751

 

A flaw was found in the way the Action Pack component performed MIME

type lookups. Since queries were cached in a global cache of MIME

types, an attacker could use this flaw to grow the cache indefinitely,

potentially resulting in a denial of service.

 

CVE-2016-0752

 

A directory traversal flaw was found in the way the Action View

component searched for templates for rendering. If an application

passed untrusted input to the 'render' method, a remote,

unauthenticated attacker could use this flaw to render unexpected

files and, possibly, execute arbitrary code.

 

CVE-2016-2097

 

Crafted requests to Action View might result in rendering files from

arbitrary locations, including files beyond the application's view

directory. This vulnerability is the result of an incomplete fix of

CVE-2016-0752. This bug was found by Jyoti Singh and Tobias Kraze

from Makandra.

 

CVE-2016-2098

 

If a web applications does not properly sanitize user inputs, an

attacker might control the arguments of the render method in a

controller or a view, resulting in the possibility of executing

arbitrary ruby code. This bug was found by Tobias Kraze from

Makandra and joernchen of Phenoelit.

 

CVE-2016-6316

 

Andrew Carpenter of Critical Juncture discovered a cross-site

scripting vulnerability affecting Action View. Text declared as "HTML

safe" will not have quotes escaped when used as attribute values in

tag helpers.

 

For Debian 7 "Wheezy", these problems have been fixed in version

3.2.6-6+deb7u3.

 

We recommend that you upgrade your ruby-actionpack-3.2 packages.
