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"
