Synopsis

Multiple vulnerabilities have been discovered in Wireshark which allow for Denial of Service or remote code execution.

2. Impact Information

Background

Wireshark is a versatile network protocol analyzer.

Description

Multiple vulnerabilities have been discovered in Wireshark:

David Maciejak discovered a vulnerability in packet-usb.c in the USB dissector via a malformed USB Request Block (URB) (CVE-2008-4680).
Florent Drouin and David Maciejak reported an unspecified vulnerability in the Bluetooth RFCOMM dissector (CVE-2008-4681).
A malformed Tamos CommView capture file (aka .ncf file) with an "unknown/unexpected packet type" triggers a failed assertion in wtap.c (CVE-2008-4682).
An unchecked packet length parameter in the dissect_btacl() function in packet-bthci_acl.c in the Bluetooth ACL dissector causes an erroneous tvb_memcpy() call (CVE-2008-4683).
A vulnerability where packet-frame does not properly handle exceptions thrown by post dissectors caused by a certain series of packets (CVE-2008-4684).
Mike Davies reported a use-after-free vulnerability in the dissect_q931_cause_ie() function in packet-q931.c in the Q.931 dissector via certain packets that trigger an exception (CVE-2008-4685).
The Security Vulnerability Research Team of Bkis reported that the SMTP dissector could consume excessive amounts of CPU and memory (CVE-2008-5285).
The vendor reported that the WLCCP dissector could go into an infinite loop (CVE-2008-6472).
babi discovered a buffer overflow in wiretap/netscreen.c via a malformed NetScreen snoop file (CVE-2009-0599).
A specially crafted Tektronix K12 text capture file can cause an application crash (CVE-2009-0600).
A format string vulnerability via format string specifiers in the HOME environment variable (CVE-2009-0601).
THCX Labs reported a format string vulnerability in the PROFINET/DCP (PN-DCP) dissector via a PN-DCP packet with format string specifiers in the station name (CVE-2009-1210).
An unspecified vulnerability with unknown impact and attack vectors (CVE-2009-1266).
Marty Adkins and Chris Maynard discovered a parsing error in the dissector for the Check Point High-Availability Protocol (CPHAP) (CVE-2009-1268).
Magnus Homann discovered a parsing error when loading a Tektronix .rf5 file (CVE-2009-1269).
The vendor reported that the PCNFSD dissector could crash (CVE-2009-1829).

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 which can trigger a Denial of Service (application crash or excessive CPU and memory usage) and possibly allow for the execution of arbitrary code with the privileges of the user running Wireshark.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All Wireshark users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-1.0.8"
