Summary:
A vulnerability exists in Solaris snoop such that a remote attacker could gain superuser access when used with the RPC service rquotad

--
Impact:
Remote super user access leading to a compromise of the target machine along with any network resources that machine is connected to.

--
Detailed Information:
Certain versions of the Solaris operating system use a program to monitor network traffic called Snoop. This program contains a flaw such that under certain conditions a buffer overflow can be caused by a remote attacker.

One such condition occurs when snoop tries to decode GETQUOTA requests to the RPC service rquotad. This daemon sends information regarding disk quotas on multi-user systems using remotely mounted shares via NFS. A specially crafted long request will trigger this overflow resulting in root access on the victim host.

--
Affected Systems:
Sun Solaris 2.4 _x86
Sun Solaris 2.4
Sun Solaris 2.5 _x86
Sun Solaris 2.5
Sun Solaris 2.5.1 _x86
Sun Solaris 2.5.1 _ppc
Sun Solaris 2.5.1
Sun Solaris 2.6 _x86
Sun Solaris 2.6
Sun Solaris 7.0 _x86
Sun Solaris 7.0

--
Attack Scenarios:
An attacker can send a specially crafted long request to snoop via the rpc.rquotad service such that it will generate a buffer overflow.

--
Ease of Attack:
Simple although a requirement is that snoop should be running at the time of attack.

--
False Positives:
None Known

--
False Negatives:
None Known

--
Corrective Action:
Patches are available for all operating systems and platforms listed as affected from Sun. These patches should be applied as soon as possible.
