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 lt; 0.10.11 gt;= 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 "gt;=net-analyzer/ethereal-0.10.11"
