Synopsis
========

Ethereal is vulnerable to numerous vulnerabilities potentially
resulting in the execution of arbitrary code or abnormal termination.

Background
==========

Ethereal is a feature rich network protocol analyzer.

Affected packages
=================

    -------------------------------------------------------------------
     Package                /  Vulnerable  /                Unaffected
    -------------------------------------------------------------------
  1  net-analyzer/ethereal      < 0.10.11                   >= 0.10.11

Description
===========

There are numerous vulnerabilities in versions of Ethereal prior to
0.10.11, including:

* The ANSI A and DHCP dissectors are vulnerable to format string
  vulnerabilities.

* The DISTCC, FCELS, SIP, ISIS, CMIP, CMP, CMS, CRMF, ESS, OCSP,
  PKIX1Explitit, PKIX Qualified, X.509, Q.931, MEGACO, NCP, ISUP, TCAP
  and Presentation dissectors are vulnerable to buffer overflows.

* The KINK, WSP, SMB Mailslot, H.245, MGCP, Q.931, RPC, GSM and SMB
  NETLOGON dissectors are vulnerable to pointer handling errors.

* The LMP, KINK, MGCP, RSVP, SRVLOC, EIGRP, MEGACO, DLSw, NCP and
  L2TP dissectors are vulnerable to looping problems.

* The Telnet and DHCP dissectors could abort.

* The TZSP, Bittorrent, SMB, MGCP and ISUP dissectors could cause a
  segmentation fault.

* The WSP, 802.3 Slow protocols, BER, SMB Mailslot, SMB, NDPS, IAX2,
  RADIUS, SMB PIPE, MRDISC and TCAP dissectors could throw assertions.

* The DICOM, NDPS and ICEP dissectors are vulnerable to memory
  handling errors.

* The GSM MAP, AIM, Fibre Channel,SRVLOC, NDPS, LDAP and NTLMSSP
  dissectors could terminate abnormallly.

Impact
======

An attacker might be able to use these vulnerabilities to crash
Ethereal and execute arbitrary code with the permissions of the user
running Ethereal, which could be the root user.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Ethereal users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.11"
