|
Date: Jan 14 2005
|
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.

PACKAGE : ethereal
SUMMARY : Fixes for security vulnerabilities in ethereal

DESCRIPTION
Ethereal[1] is a powerful network traffic analyzer with a graphical
user interface (GUI).
This update fixes several vulnerabilities[2,3,4] in ethereal:
CAN-2004-0633[5]: The iSNS dissector for ethereal 0.10.3 through
0.10.4 allows remote attackers to cause a denial of service (process
abort) via an integer overflow.
CAN-2004-0634[6]: The SMB SID snooping capability in ethereal 0.9.15
to 0.10.4 allows remote attackers to cause a denial of service
(process abort) via a handle without a policy name, which causes a
null dereference.
CAN-2004-0635[7]: The SNMP dissector in ethereal 0.8.15 through
0.10.4 allows remote attackers to cause a denial of service (process
abort) via a malformed request or by missing community string, which
causes an out-of-bounds read.
CAN-2004-0504[8]: ethereal 0.10.3 allows remote attackers to cause a
denial of service (crash) via certain SIP messages between Hotsip
servers and clients.
CAN-2004-0505[9]: The AIM dissector in ethereal 0.10.3 allows remote
attackers to cause a denial of service (assert error).
CAN-2004-0506[10]: The SPNEGO dissector in ethereal 0.9.8 to 0.10.3
allows remote attackers to cause a denial of service (abort).
CAN-2004-0507[11]: Buffer overflow in the MMSE dissector for ethereal
0.10.1 to 0.10.3 allows remote attackers to cause a denial of service
and possibly execute arbitrary code.
CAN-2004-1139[12]: Matthew Bing found a problem in DICOM dissection
that could make Ethereal exit unexpectedly.
CAN-2004-1140[13]: An invalid RTP timestamp could make Ethereal hang
and create a large temporary file, possibly filling all available
disk space.
CAN-2004-1141[14]: The HTTP dissector could access previously-freed
memory, making Ethereal exit unexpectedly.
CAN-2004-1142[15]: Brian Caswell discovered that an improperly
formatted SMB packet could make Ethereal hang, maximizing CPU
utilization.
SOLUTION
It is recommended that all ethereal users upgrade their packages.
