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.
