SA Document Body
Multiple Security Issues in the Doors Kernel Functionality
1. Impact
Multiple security vulnerabilities exist in the Doors subsystem of the
Solaris kernel which may allow a local unprivileged user to hang any
door server process, which is a type of Denial of Service (DoS).
These issues may also allow a local unprivileged user or a privileged
user in a non-global zone the ability to access files without the
necessary permissions or to potentially execute arbitrary code in the
kernel context.
2. Contributing Factors
These issues can occur in the following releases:
SPARC Platform
* Solaris 8 without patch 117350-61
* Solaris 9 without patch 122300-37
* Solaris 10 without patch 137137-05
* OpenSolaris based upon builds snv_01 through snv_93
x86 Platform
* Solaris 8 without patch 117351-61
* Solaris 9 without patch 122301-37
* Solaris 10 without patch 137138-05
* OpenSolaris based upon builds snv_01 through snv_93
Note: 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_96
To identify if a process uses the Doors facility as a server, the
following command can be run:
# pfiles [pid] | grep 'door to'
O_RDWR FD_CLOEXEC door to yourProcess[pid]
3. Symptoms
There are no predictable symptoms that would indicate the described
vulnerabilities have been exploited.
4. 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 8 with patch 117350-61 or later
* Solaris 9 with patch 122300-37 or later
* Solaris 10 with patch 137137-05 or later
* OpenSolaris based upon builds snv_94 or later
x86 Platform
* Solaris 8 with patch 117351-61 or later
* Solaris 9 with patch 122301-37 or later
* Solaris 10 with patch 137138-05 or later
* OpenSolaris based upon builds snv_94 or later
