Synopsis

========

 

Multiple Denial of Service vulnerabilities have been discovered in

Wireshark.

 

Background

==========

 

Wireshark is a network protocol analyzer with a graphical front-end.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 net-analyzer/wireshark < 1.0.3 >= 1.0.3

 

Description

===========

 

The following vulnerabilities were reported:

 

* Multiple buffer overflows in the NCP dissector (CVE-2008-3146).

 

* Infinite loop in the NCP dissector (CVE-2008-3932).

 

* Invalid read in the tvb_uncompress() function when processing zlib

compressed data (CVE-2008-3933).

 

* Unspecified error when processing Textronix .rf5 files

(CVE-2008-3934).

 

Impact

======

 

A remote attacker could exploit these vulnerabilities by sending

specially crafted packets on a network being monitored by Wireshark or

by enticing a user to read a malformed packet trace file, causing a

Denial of Service.

 

Workaround

==========

 

There is no known workaround at this time.

 

Resolution

==========

 

All Wireshark users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-1.0.3"
