Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
Multiple Denial of Service vulnerabilities have been discovered in
Wireshark.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Wireshark is a network protocol analyzer with a graphical front-end.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
-------------------------------------------------------------------=
Package / Vulnerable / Unaffected
-------------------------------------------------------------------=
1 net-analyzer/wireshark < 1.0.3 >=3D 1.0.=

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
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
=3D=3D=3D=3D=3D=3D
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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All Wireshark users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dnet-analyzer/wireshark-1.0.=
3"
