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.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Wireshark users should upgrade to the latest version:
Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us. Any security concerns should be addressed to security@gentoo.org or alternatively, you may file a bug at http://bugs.gentoo.org.
