<title>Wireshark: Multiple Denials of Service</title>
Multiple Denial of Service vulnerabilities have been discovered in
<product type="ebuild">wireshark</product>

<revised>September 25, 2008: 01</revised>

Wireshark is a network protocol analyzer with a graphical front-end.
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
<impact type="normal">
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.
There is no known workaround at this time.
All Wireshark users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-analyzer/wireshark-1.0.3&quot;</code>
