Solution Type: Sun Alert
Solution 256788 : Multiple Security Vulnerabilities in Adobe Reader
for Solaris 10 May Allow Execution of Arbitrary Code or Cause a Denial
of Service (DoS) (Adobe Security Bulletin APSB09-04)
Bug ID: 6816953
Product
Solaris 10 Operating System
SA Document Body
Multiple Security Vulnerabilities in Adobe Reader for Solaris 10 May
Allow Execution of Arbitrary Code or Cause a Denial of Service (DoS)
(Adobe Security Bulletin APSB09-04)
1. Impact
Multiple security vulnerabilities in Adobe Reader 9.0 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.
These issues are also described in the following documents:

CVE-2009-1062 at
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1062
2. Contributing Factors
These issues can occur in the following release:
SPARC Platform
* Solaris 10
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 9.0 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.
For the buffer overflow vulnerability described in CVE-2009-0658:
Disabling JavaScript may prevent this vulnerability from being
exploited. Acrobat JavaScript can be disabled in the General
preferences dialog of Adobe Reader with the following:
1. Edit -> Preferences -> JavaScript
2. Un-check Enable Acrobat JavaScript
Note that this workaround will not prevent the vulnerability from
being exploited, but will only prevent one of the most common exploits
used against this vulnerability.
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.
In addition, the risk of these vulnerabilities can mitigated by
disabling JavaScript in Adobe Reader as mentioned above. JavaScript is
not necessary for these vulnerabilities to be exploited, but if
JavaScript is disabled it is typically more difficult to do so.
Interim Security Relief (ISR) is available from
http://sunsolve.sun.com/tpatches for the following release:
SPARC Platform
* Solaris 10 IDR141324-01
