PLATFORM: Ethereal versions prior to 0.10.9 Debian GNU/Linux 3.0 (woody) Red Hat Desktop (v. 3) and (v. 4) Red Hat Enterprise Linux AS, ES, WS (v. 2.1, v.3 and v.4) Red Hat Linux Advanced Workstation 2.1 for the Itanium Processor SGI ProPack 3 Service Pack 3 DAMAGE: CAN-2005-0006: The COPS dissector could go into an infinite loop. CAN-2005-0007: The DLSw dissector could cause an assertion, making Ethereal exit prematurely. CAN-2005-0008: The DNP dissector could cause memory corruption. CAN-2005-0009: The Gnutella dissector could cause an assertion, making Ethereal exit prematurely. CAN-2005-0010: The MMSE dissector could free static memory. CAN-2005-0084: The X11 protocol dissector is vulnerable to a string buffer overflow. SOLUTION: Apply the security update. ______________________________________________________________________________ VULNERABILITY The risk is HIGH.
