Gentoo Linux Security Advisory

Title: Wireshark: Multiple Denials of Service (GLSA 200809-17)
Severity: normal
Exploitable: remote
Date: September 25, 2008
Bug(s): #236515
ID: 200809-17

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: net-analyzer/wireshark
Vulnerable: < 1.0.3
Unaffected: >= 1.0.3
Architectures: All supported architectures


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