iDefense Security Advisory 08.04.08
Aug 04, 2008
The snoop command line utility is installed by default on Solaris. It is
used to capture and display network traffic, similar to the widely used
tcpdump program. Server Message Block (SMB), is a network protocol used
for Microsoft Windows file sharing. More information can be found on the
vendor's website at the following URL.
Remote exploitation of multiple stack-based buffer overflow
vulnerabilities in Sun Microsystems Inc.'s snoop could allow an
attacker to execute arbitrary code with the privileges of the nobody
Multiple buffer overflow vulnerabilities exist within the code that
parses and displays SMB traffic. In most cases, exploitation is trivial
as an attacker has full control of the data copied.
Exploitation of these vulnerabilities results in the execution of
arbitrary code with the privileges of the nobody user. In addition, the
attacker has access to the raw socket used by the snoop program. This
allows them to capture any traffic visible to the network interface
Often in client-side vulnerabilities, an attacker only has a single
chance to exploit the vulnerability. However, the snoop utility will
handle any segmentation violations and attempt to continue capturing
network traffic. This gives an attacker multiple opportunities to
exploit a vulnerability, which increases the likelihood of successful
iDefense has confirmed the existence of these vulnerabilities in snoop
for Solaris 10 8/07. Other versions may also be affected.
iDefense is currently unaware of any workarounds for these issues.
