Date: Wed, 31 Mar 2004 17:51:53 -0300 From: Conectiva Updates <secure@...ectiva.com.br> To: conectiva-updates@...aleguas.conectiva.com.br, lwn@....net, bugtraq@...urityfocus.com, security-alerts@...uxsecurity.com, linsec@...ts.seifried.org Subject: [CLA-2004:835] Conectiva Security Announcement - ethereal -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : ethereal SUMMARY : Several remote vulnerabilities DATE : 2004-03-31 17:50:00 ID : CLA-2004:835 RELEVANT RELEASES : 8, 9 - ------------------------------------------------------------------------- DESCRIPTION Ethereal[1] is a powerful network traffic analyzer with a graphical user interface (GUI). This update fixes several vulnerabilities[2] in Ethereal: CAN-2004-0176: Stefan Esser discovered thirteen buffer overflows in the dissector of the NetFlow, IGAP, EIGRP, PGM, IrDA, BGP, ISUP, and TCAP protocol dissectors[3]. CAN-2004-0365: Jonathan Heussser discovered a denial of service vulnerability in the RADIUS protocol dissector[4]. CAN-2004-0367: A zero-length presentation protocol selector can be exploited to cause a denial of service[5]. These vulnerabilities can be exploited by a attacker who is able to insert crafted packets in the wire being monitored by ethereal or make an user open a trace file with such packets inside. When reading this data, Ethereal will crash (characterizing a denial of service condition) or, in the case of the buffer overflow vulnerabilities, may execute arbitrary code with the privileges of the user running it (usually root). SOLUTION It is recommended that all Ethereal users upgrade their packages.
