CONECTIVA LINUX SECURITY ANNOUNCEMENT
- --------------------------------------------------------------------------
PACKAGE : ethereal
SUMMARY : Fixes for security vulnerabilities in ethereal
DATE : 2005-01-13 11:44:00
ID : CLA-2005:916
RELEVANT
RELEASES : 9, 10

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.
