SA Document Body
A Security Vulnerability in the namefs Kernel module may result in
Arbitrary Code Execution or a Denial of Service (DoS)
1. Impact
A security vulnerability in the namefs kernel module may allow a local
unprivileged user the ability to execute arbitrary code in kernel
context or panic the system. The ability to panic the system is a type
of Denial of Service (DoS).
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
* Solaris 8 without patch 114984-02
* Solaris 9 without patch 114971-03
* Solaris 10 without patch 136716-01
x86 Platform
* Solaris 8 without patch 114985-02
* Solaris 9 without patch 138570-01
* Solaris 10 without patch 136717-01
3. Symptoms
There are no predictable symptoms that would indicate that the issue
has been exploited to execute arbitrary code. In the case of a Denial
of Service (DoS), system panics will vary if this issue is exploited.
Typically, the type of panic is one of "BAD TRAP".
4. Workaround
There is no workaround for this issue. Please see the Resolution
section below.
5. Resolution
SPARC Platform
* Solaris 8 with patch 114984-02 or later
* Solaris 9 with patch 114971-03 or later
* Solaris 10 with patch 136716-01 or later
x86 Platform
* Solaris 8 with patch 114985-02 or later
* Solaris 9 with patch 138570-01 or later
* Solaris 10 with patch 136717-01 or later
