Sun(sm) Alert Notification
* Sun Alert ID: 102711
* Synopsis: Security Vulnerabilities in OpenSSL May Lead to a Denial
of Service (DoS) to Applications or Execution of Arbitrary Code
With Elevated Privileges
* Category: Security
* Product: Solaris 10 Operating System
* BugIDs: 6466370
* Avoidance: Patch
* State: Resolved
* Date Released: 09-Nov-2006, 08-Nov-2007
* Date Closed: 08-Nov-2007
* Date Modified: 13-Nov-2006, 26-Jun-2007, 08-Nov-2007, 03-Dec-2007
1. Impact
Two security vulnerabilities in the OpenSSL product (see openssl(5))
shipped with Solaris 10 may affect applications which make use of this
product. Depending on the individual application, the first issue may
allow a local or remote unprivileged user to execute arbitrary code
with the privileges of the user running the application.
The second issue may allow a remote user who controls a server to
which an application connects to crash that application, causing a
Denial of Service (DoS) condition.
These issues are also referenced in the following documents:

http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4343
Sun wishes to acknowledge with thanks, Tavis Ormandy and Will Drewry
(Google Security Team) for bringing these issues to our attention.
2. Contributing Factors
These issues can occur in the following releases:
SPARC Platform
* Solaris 10 without patches 121229-02 and 118562-13
x86 Platform
* Solaris 10 without patches 121230-02 and 118563-13
Notes:
1. Systems which do not have the domestic/strong encryption packages
SUNWcry + SUNWcryr installed, will only have the libss patches
121229-02/121230-02 installed.
To determine if these packages are installed, the following command
can be run
$ pkginfo SUNWcry SUNWcryr
2. Solaris 8 does not include the OpenSSL toolkit, and therefore is
not vulnerable to this issue.
3. Solaris 9 does not ship with OpenSSL libraries which can be used
for application linking and the applications that are shipped with
Solaris 9 which make use of OpenSSL via static linking are not
vulnerable to this issue.
3. Symptoms
There are no predictable symptoms which would indicate that the first
issue mentioned above has been exploited to gain elevated privileges.
If the second issue has been exploited, the affected application will
no longer be available. Depending on the system configuration, core
files may be created and application crashes may be recorded in system
logs.
4. Relief/Workaround
There is no workaround for these issues. Please see the Resolution
section below.
5. Resolution
These issues are addressed in the following releases:
SPARC Platform
* Solaris 10 with (libssl) patch 121229-02 or later and patch
118562-13 or later
x86 Platform
* Solaris 10 with (libssl) patch 121230-02 or later and patch
118563-13 or later
Note: Both patches listed above are required to fully resolve this
issue on Solaris 10 systems which have the Data Encryption Kit
installed. To determine if the Data Encryption Kit is installed on a
system, the presence of the SUNWcry package can be checked by running
the following command:
$ pkginfo SUNWcry
system SUNWcry Crypt Utilities
