Product
Solaris 10 Operating System

Bug Id
6466370

Date of Workaround Release
09-NOV-2006

Date of Resolved Release
08-NOV-2007

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:

CVE-2006-3738 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3738

CVE-2006-4343 at 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.

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.

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.

Workaround

There is no workaround for these issues. Please see the Resolution section below.

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
