Date of Resolved Release: 30-Jul-2008
SA Document Body
A Security Vulnerability in picld(1M) May Allow a Denial of Service to
System Monitoring and System Services
1. Impact
Due to a security vulnerability in the Solaris Platform Information
and Control Library daemon (picld(1M)), a local unprivileged user may
be able to disable system monitoring and prevent system utilities
(prtdiag(1M), prtpicl(1M), prtfru(1M)) from operating properly. This
is a type of Denial of Service (DoS).
2. Contributing Factors
This can occur in the following releases:
SPARC Platform:
* Solaris 8 (10/00 or later) without patch 112169-07
* Solaris 9 without patch 137400-01
* Solaris 10 without patch 138068-01
* OpenSolaris based upon builds snv_01 through snv_95
x86 Platform:
* Solaris 9 without patch 137401-01
* Solaris 10 without patch 138069-01
* OpenSolaris based upon builds snv_01 through snv_95
Notes:
1. Solaris 8 on the x86 platform is not impacted by this issue
2. Only OpenSolaris installations including the affected binary below
are impacted by this issue.
/usr/lib/picl/picld
3. 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 -a
SunOS phys-node-1 5.11 snv_86 i86pc i386 i86pc
3. Symptoms
If this issue has been exploited to cause a Denial of Service,
invocations of prtpicl(1M), prtfru(1M) and prtdiag(1M) will not run to
completion and will not display information that is normally seen.
4. Workaround
There is no workaround that would prevent this issue from being
exploited.
If the issue has been exploited, it is possible to recover from the
Denial of Service state by stopping and restarting picld(1M) by doing
the following:
For Solaris 10, issue the following command:
# svcadm restart picl
For Solaris 9 and 8, issue the following commands:
# /etc/init.d/picld stop
# /etc/init.d/picld start
5. Resolution
This issue is addressed in the following releases:
SPARC Platform:
* Solaris 8 with patch 112169-07 or later
* Solaris 9 with patch 137400-01 or later
* Solaris 10 with patch 138068-01 or later
* OpenSolaris based upon builds snv_96 or later
x86 Platform:
* Solaris 9 with patch 137401-01 or later
* Solaris 10 with patch 138069-01 or later
* OpenSolaris based upon builds snv_96 or later
