Ethereal SIP, AIM, SPNEGO, and MMSE Dissector Flaws Allow Remote Users to Crash Ethereal or Execute Arbitrary Code
SecurityTracker Alert ID:  1010158
SecurityTracker URL:  http://securitytracker.com/id/1010158
CVE Reference:   CAN-2004-0504, CAN-2004-0505, CAN-2004-0506, CAN-2004-0507   (Links to External Site)
Updated:  Jun 5 2004
Original Entry Date:  May 14 2004
Impact:   Denial of service via network, Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 0.9.8 up to and including 0.10.3
Description:   Several vulnerabilities were reported in Ethereal, affecting the SIP, AIM, SPNEGO, and MMSE dissectors. A remote user can cause denial of service conditions or execute arbitrary code on the target system.

The vendor reported that several protocol dissectors contain flaws that may allow a remote user to cause Ethereal to crash or to execute arbitrary code.

It is reported that a remote user can send a SIP packet that will, under certain conditions, cause Ethereal to crash [CVE: CAN-2004-0504]. Only version 0.10.3 is affected, the report said. Details on the conditions required to trigger the flaw are provided at:

http://www.ethereal.com/lists/ethereal-users/200405/msg00018.html

It is also reported that a remote user can cause the AIM dissector to throw an assertion and cause Ethereal to crash [CVE: CAN-2004-0505]. Only version 0.10.3 is affected, the report said.

It is also reported that a remote user can trigger a null pointer dereference in the SPNEGO dissector and cause Ethereal to crash [CVE: CAN-2004-0506].

It is also reported that there is a buffer overflow in the MMSE dissector [CVE: CAN-2004-0507]. Versions 0.10.1 to 0.10.3 are affected. A remote user can cause arbitrary code to be executed by the Ethereal process.

These flaws can be triggered by a remote user sending malformed traffic through a network that is monitored by Ethereal, via a malformed packet trace file, or via a malformed color filter file.

Impact:   A remote user can cause Ethereal to crash. A remote user can cause Ethereal to execute arbitrary code with the privileges of the Ethereal process.
Solution:   The vendor has issued a fixed version (0.10.4), available at:

http://www.ethereal.com/download.html

For users of versions prior to 0.10.4 that cannot upgrade, the report indicates that you can disable all of the protocol dissectors listed above by selecting Analyze->Enabled Protocols... and deselecting them from the list.
