INFORMATION BULLETIN
Ethereal Multiple Problems in 0.10.4
[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
(0.10.3-0.10.4);
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.
