                   [Ethereal Application Note enpa-sa-00015]

July 8, 2004 16:00 GMT                                            Number O-174
PROBLEM:       There are 3 issues that were discovered in the following 
               protocol dissectors: 
			   1) The iSNS dissector could make Ethereal abort in some cases 
			   2) SMB SID snooping could crash if there was no policy name for 
			   a handle (0.9.15-0.10.4); 
			   3) The SNMP dissector could crash due to a malformed or missing 
               community string (0.8.15-0.10.4) 
PLATFORM:      Ethereal 0.8.15 up to and including 0.10.4 
DAMAGE:        It may be possible to make Ethereal crash or run arbitrary code 
               by injecting a purposefully malformed packet onto the wire or 
               by convincing someone to read a malformed packet trace file. 
SOLUTION:      Upgrade to 0.10.5 
VULNERABILITY  The risk is HIGH. Ethereal is a widely used packet sniffer and 
ASSESSMENT:    must be run as root. It may be possible to run arbitrary code 
               or cause a crash.
