-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : ethereal SUMMARY : Fix for ethereal vulnerabilities DATE : 2003-11-07 16:08:00 ID : CLA-2003:780 RELEVANT RELEASES : 7.0, 8, 9 - ------------------------------------------------------------------------- DESCRIPTION Ethereal[1] is a powerful network traffic analyzer with a graphical user interface (GUI). This update announcement addresses several vulnerabilities[2] in ethereal versions prior to 0.9.16. These vulnerabilities can be exploited by an attacker who can insert crafted packets in the wire being monitored by ethereal or make an user open a trace file with such packets inside. Successful exploitation of these vulnerabilities can lead to denial of service conditions and/or remote execution of arbitrary code. The following vulnerabilities have been fixed in the 0.9.16 version: - buffer overflow in the GTP protocol dissector (CAN-2003-0925)[3] - denial of service with ISAKMP or MEGACO packets (CAN-2003-0926)[4] - buffer overflow in the SOCKS protocol dissector (CAN-2003-0927)[5] SOLUTION It is recommended that all ethereal users upgrade their packages.
