Synopsis
========
Adobe Reader is vulnerable to execution of arbitrary code.
Background
==========
Adobe Reader (formerly Adobe Acrobat Reader) is a closed-source PDF
reader.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-text/acroread < 8.1.4 >= 8.1.4
Description
===========
Multiple vulnerabilities have been discovered in Adobe Reader:
* Alin Rad Pop of Secunia Research reported a heap-based buffer
overflow when processing PDF files containing a malformed JBIG2
symbol dictionary segment (CVE-2009-0193).
* A buffer overflow related to a non-JavaScript function call and
possibly an embedded JBIG2 image stream has been reported
(CVE-2009-0658).
* Tenable Network Security reported a stack-based buffer overflow
that can be triggered via a crafted argument to the getIcon() method
of a Collab object (CVE-2009-0927).
* Sean Larsson of iDefense Labs reported a heap-based buffer overflow
when processing a PDF file containing a JBIG2 stream with a size
inconsistency related to an unspecified table (CVE-2009-0928).
* Jonathan Brossard of the iViZ Security Research Team reported an
unspecified vulnerability related to JBIG2 and input validation
(CVE-2009-1061).
* Will Dormann of CERT/CC reported a vulnerability lading to memory
corruption related to JBIG2 (CVE-2009-1062).
Impact
======
A remote attacker could entice a user to open a specially crafted PDF
document, possibly leading to the execution of arbitrary code with the
privileges of the user running the application, or a Denial of Service.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Adobe Reader users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/acroread-8.1.4"
