Security Vulnerability in Solaris 10 OpenSSL SSL_get_shared_ciphers() Function

1. Impact

A security vulnerability in the SSL_get_shared_ciphers() function within the OpenSSL library shipped with Solaris 10 may affect applications which make use of this function. The exact impact will vary depending on the way this function is used by the application. For example, if the application communicates with remote hosts and makes use of the SSL_get_shared_ciphers() function, it may be possible for a local or remote user to execute arbitrary code with the privileges of the impacted application or to cause the application to crash, which is a type of Denial of Service (DoS).

This issue is also referenced in the following documents:

CVE-2007-5135 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5135

2. Contributing Factors

This issue can occur in the following releases:

SPARC Platform

• Solaris 10 without patch 127111-08

x86 Platform

• Solaris 10 without patch 127112-08

Notes:

1. Solaris 8 does not include the OpenSSL toolkit, and therefore is not vulnerable to this issue.
2. Solaris 9 does not ship with OpenSSL libraries which can be used for third-party application linking. The applications that are shipped with Solaris 9 and which are statically linked with OpenSSLare not vulnerable to this issue.

3. Symptoms

There are no predictable symptoms that would indicate that this issue has been exploited to gain elevated privileges. Symptoms indicating a Denial of Service (DoS) will vary depending upon the application.

4. Workaround

There is no workaround for this issue. However, affected applications may allow this issue to be worked around by disabling the functionality which makes use of the SSL_get_shared_ciphers() function (for example, SSL support). See the relevant application documentation for further information.

Resolution

This issue is addressed in the following releases:

SPARC Platform

• Solaris 10 with patch 127111-08 or later
  

x86 Platform

• Solaris 10 with patch 127112-08 or later
