Adobe Reader (formerly Adobe Acrobat Reader) is a closed-source PDF
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
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
Will Dormann of CERT/CC reported a vulnerability lading to memory
corruption related to JBIG2 (CVE-2009-1062).
</ul> <p>
<impact type="normal">
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.
There is no known workaround at this time.
All Adobe Reader users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-text/acroread-8.1.4&quot;</code>
