1. Impact
A remote privileged user may be able to attempt an IKE exchange using
a malformed payload, which could cause the in.iked(1M) process to
crash, causing a Denial of Service (DoS) of IPSec key management
services.
This issue is revealed by the test suite which is described in NISCC
vulnerability #273756, which is available at
http://www.uniras.gov.uk/niscc/docs/br-20051114-01013.html?lang=en
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
* Solaris 9
* Solaris 10
x86 Platform
* Solaris 9
* Solaris 10
Notes:
1. Solaris 8 is not affected by this issue.
2. The described issue only affects systems running the IKE (Internet
Key Exchange) daemon in.iked(1M).
To determine if the in.iked(1M) is running on a system, the following
command can be run:
# pgrep -l in.iked
368 in.iked
3. Symptoms
If this issue has been exploited, the IKE daemon would no longer be
running. To determine that the IKE (in.iked(1M)) daemon is NOT running
on a system, the following command can be run:
$ pgrep in.iked || echo "in.iked not running"
