-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- 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.
