Some vulnerabilities have been reported in Sun Solaris, which can be exploited by malicious people to compromise a user's system.

1) Some boundary errors exist within the snoop(1M) network utility when parsing and displaying SMB traffic. This can be exploited to cause stack-based buffer overflows and allows execution of arbitrary code as the "snoop" user when a specially crafted packet is captured or read via the "-i" option.

2) Some format string errors within the snoop(1M) network utility when parsing and displaying SMB traffic can be exploited to execute arbitrary code.

Successful exploitation requires that "snoop" is used without the "-o" command line option.

NOTE: If "snoop" is invoked as "root", the effective user is changed to "nobody".

The vulnerabilities are reported in Solaris 8, 9, and 10 for both the SPARC and x86 platforms.
