Gentoo Linux Security Advisory

Title: Adobe Acrobat Reader: Multiple vulnerabilities (GLSA 200701-16)
Severity: normal
Exploitable: remote
Date: January 22, 2007
Bug(s): #159874
ID: 200701-16

Synopsis

Adobe Acrobat Reader is vulnerable to remote code execution, Denial of Service, and cross-site scripting attacks.

Background

Adobe Acrobat Reader is a PDF reader released by Adobe.

Affected Packages

Package: app-text/acroread
Vulnerable: < 7.0.9
Unaffected: >= 7.0.9
Architectures: All supported architectures


Description

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 plugin released with Adobe Acrobat Reader (nppdf.so) does not properly handle URLs, and crashes if given a URL that is too long. The plugin does not correctly handle JavaScript, and executes JavaScript that is given as a GET variable to the URL of a PDF file. Lastly, the plugin does not properly handle the FDF, xml, xfdf AJAX request parameters following the # character in a URL, allowing for multiple cross-site scripting vulnerabilities.

Impact

An attacker 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. An attacker could also entice a user to browse to a specially crafted URL and either crash the Adobe Acrobat Reader browser plugin, 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 "nsplugin" USE flag disabled are not vulnerable to issues with the Adobe Acrobat Reader browser plugin.

Workaround

There is no known workaround at this time.

Resolution

All Adobe Acrobat Reader users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/acroread-7.0.9"
