[GLSA-200701-16] Adobe Acrobat Reader: Multiple vulnerabilities

Vulnerability Assessment Summary
Adobe Acrobat Reader: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200701-16
(Adobe Acrobat Reader: Multiple vulnerabilities)

Adobe Acrobat Reader in stand-alone mode is vulnerable to remote code
execution via heap corruption when loading a specially crafted PDF
file.
The browser test released with Adobe Acrobat Reader (nppdf.so) does
not properly handle URLs, and crashes if given a URL that is too long.
The test does not correctly handle JavaScript, and executes
JavaScript that is given as a GET variable to the URL of a PDF file.
Lastly, the test does not properly handle the FDF, xml, xfdf AJAX
request parameters following the # character in a URL, permiting for
multiple cross-site scripting vulnerabilities.

Impact

A possible hacker could entice a user to open a specially crafted PDF file
and execute arbitrary code with the rights of the user running Adobe
Acrobat Reader. A possible hacker could also entice a user to browse to a
specially crafted URL and either crash the Adobe Acrobat Reader browser
test, execute arbitrary JavaScript in the context of the user's
browser, or inject arbitrary HTML or JavaScript into the document being
viewed by the user. Note that users who have emerged Adobe Acrobat
Reader with the "nstest" USE flag disabled are not vulnerable to
issues with the Adobe Acrobat Reader browser test.

Workaround

There is no known workaround at this time.
