GLSA-200501-27 : Ethereal: Multiple vulnerabilities

high Nessus Plugin ID 16418

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200501-27 (Ethereal: Multiple vulnerabilities)

 There are multiple vulnerabilities in versions of Ethereal earlier than 0.10.9, including:
 The COPS dissector could go into an infinite loop (CAN-2005-0006).
 The DLSw dissector could cause an assertion, making Ethereal exit prematurely (CAN-2005-0007).
 The DNP dissector could cause memory corruption (CAN-2005-0008).
 The Gnutella dissector could cause an assertion, making Ethereal exit prematurely (CAN-2005-0009).
 The MMSE dissector could free statically-allocated memory (CAN-2005-0010).
 The X11 dissector is vulnerable to a string buffer overflow (CAN-2005-0084).
 Impact :

 An attacker might be able to use these vulnerabilities to crash Ethereal, perform DoS by CPU and disk space utilization or even execute arbitrary code with the permissions of the user running Ethereal, which could be the root user.
 Workaround :

 For a temporary workaround you can disable all affected protocol dissectors by selecting Analyze->Enabled Protocols... and deselecting them from the list. However, it is strongly recommended to upgrade to the latest stable version.

Solution

All Ethereal users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-analyzer/ethereal-0.10.9'
