for Solaris 10 May Allow Execution of Arbitrary Code or Cause Denial
of Service (DoS)
Bug ID: 6836837
Product:
Solaris 10 Operating System
Date of Workaround Release: 13-May-2009
Date of Resolved Release: 02-Sep-2009
SA Document Body
Multiple Security Vulnerabilities in Adobe Reader for Solaris 10 ...
see below for full details:
1. Impact
Multiple security vulnerabilities in Adobe Reader 9.1 and earlier for
Solaris 10 may allow remote unprivileged users to execute arbitrary
code
or crash the Adobe Reader application, thereby causing a Denial of
Service (DoS) condition. These vulnerabilities may be exploited via
specially crafted PDF files.
Following resources document these issues in more detail.

* APSB09-06 at

* CVE-2009-1492 at
http://cve.mitre.org/cgi-bin/cvename.cgi?name=2009-1492
* CVE-2009-1493 at
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1493
2. Contributing Factors
These issues can occur in the following release:
SPARC Platform
* Solaris 10 without patch 121104-08
Notes:
1. Solaris 8, Solaris 9, Solaris 10 on the x86 platform and
OpenSolaris
do not ship Adobe Reader and therefore are not affected by this issue.
2. All versions of Adobe Reader up to and including version 7.0.9 and
versions 8.0 through 9.1 are affected by these issues.
To determine the version of Adobe Reader installed on the system, the
following command can be run:
$ /usr/bin/acroread -version
7.0.1
Earlier versions of Adobe Reader on Solaris 10 only shipped acroread
in
/usr/sfw/bin which do not support the '-version' option, so for such
instances, the following command can be used instead:
$ cat `pkgchk -l -P AcroVersion | awk '/Pathname/ { print $2 }'`
5.0.10
3. Symptoms
If the described issues have been exploited to cause a Denial of
Service
(DoS), the Adobe Reader application will crash, potentially leaving a
core file depending on the system configuration.
There are no predictable symptoms that would indicate that these
issues
have been exploited to execute arbitrary code.
4. Workaround
To avoid the described issues, do not load PDF files from untrusted
sources.
Disabling JavaScript prevents these vulnerabilities from being
exploited. Acrobat JavaScript can be disabled in the General
preferences dialog of Adobe Reader with the following:
1. Edit -> Preferences
2. Select the JavaScript category.
3. Un-check 'Enable Acrobat JavaScript'
4. Click OK.
Until patches can be applied, the risk of these vulnerabilities can be
mitigated by preventing PDF documents from being opened automatically
by the Web browser. In Firefox 2.0, this can be set by changing the
default
action for PDF documents with the following:
1. Open the Preferences dialog from the Edit menu
2. Select Contents tab.
3. Click on Manage button in File Types block.
4. Select PDF in the list and click Change Action.
5. Select 'Save them on my computer' option and click OK.
Note that this workaround will reduce the risk of exploitation but
will not prevent the issue from being exploited.
5. Resolution
These issues are addressed in the following release:
SPARC Platform
* Solaris 10 with patch 121104-08 or later
