http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0590
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform:
* Solaris 10 without patch 141742-01
* OpenSolaris based upon builds snv_01 through snv_112
x86 Platform:
* Solaris 10 without patch 140119-07
* OpenSolaris based upon builds snv_01 through snv_112
Notes:
1. Solaris 8 and Solaris 9 are not impacted by this issue.
2. Any OpenSSL application which prints out the contents of a
certificate could be affected by this bug, including SSL servers,
clients and S/MIME software. For example: commands such as openssl(1)
and servers such as PostgreSQL are known to be vulnerable to this
issue.
3. Solaris Secure Shell (SSH), Firefox and Thunderbird distributed
with Solaris are not vulnerable to this issue.
OpenSolaris distributions may include additional bug fixes above and
beyond the build from which it was derived. The base build can be
derived as follows:
$ uname -v
snv_101
3. Symptoms
There are no predictable symptoms that would indicate the described
vulnerability has been exploited.
4. Workaround
There is no workaround for this issue. Please see the Resolution
section below.
5. Resolution
This issue is addressed in the following releases:
SPARC Platform:
* Solaris 10 with patch 141742-01 or later
* OpenSolaris based upon builds snv_113 or later
x86 Platform:
* Solaris 10 with patch 140119-07 or later
