Solution 247406 : Security Vulnerability with IKE Packet Handling
in Solaris libike Library may Lead to a Crash of in.iked(1M)
Bug ID: 6750947
Product
Solaris 9 Operating System
Solaris 10 Operating System
OpenSolaris
Date of Resolved Release: 22-Jan-2009
SA Document Body
A security vulnerability in IKE packet handling in the libike library:
1. Impact
A security vulnerability in IKE packet handling in the libike library
shipped with Solaris may allow a remote unprivileged user to crash the
in.iked(1M) daemon, which is a type of Denial of Service (DoS).
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
* Solaris 9 without patch 113451-15
* Solaris 10 without patch 140196-01
* Opensolaris based upon build snv_01 through snv_99
x86 Platform
* Solaris 9 without patch 114435-14
* Solaris 10 without patch 140414-01
* Opensolaris based upon build snv_01 through snv_99
Note 1: Solaris 8 is not impacted by this issue.
Note 2: OpenSolaris distributions may include additional bug fixes
above and beyond the build from which it was derived.
To determine the base build of OpenSolaris, the following command can
be used:
$ uname -v
snv_86
Note 3: The described issue only affects systems running the IKE
daemon in.iked(1M).
The in.iked(1M) daemon is configured to run on a system if the file
"/etc/inet/ike/config" is present. To determine if IKE services are
configured on the system, the following command can be run:
$ ls /etc/inet/ike/config
/etc/inet/ike/config: No such file or directory
By default, the in.iked(1M) service is disabled on Solaris systems.
3. Symptoms
If the described issue has been exploited, the IKE daemon may no
longer be running on the system.
To determine if the IKE (in.iked(1M)) daemon is not running on a
system that has IKE configured, the following command can be run:
$ pgrep in.iked || echo
"in.iked not running but should be"
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 9 with patch 113451-15 or later
* Solaris 10 with patch 140196-01 or later
* Opensolaris based upon build snv_100 or later
x86 Platform
* Solaris 9 with patch 114435-14 or later
* Solaris 10 with patch 140414-01 or later
* Opensolaris based upon build snv_100 or later
