Wireshark: Multiple vulnerabilities

Background

Wireshark is a versatile network protocol analyzer.

Description

Multiple vulnerabilities have been discovered in Wireshark:

• Ryan Giobbi reported an integer overflow in wiretap/erf.c (CVE-2009-3829).
• The vendor reported multiple unspecified vulnerabilities in the Bluetooth L2CAP, RADIUS, and MIOP dissectors (CVE-2009-2560), in the OpcUa dissector (CVE-2009-3241), in packet.c in the GSM A RR dissector (CVE-2009-3242), in the TLS dissector (CVE-2009-3243), in the Paltalk dissector (CVE-2009-3549), in the DCERPC/NT dissector (CVE-2009-3550), and in the dissect_negprot_response() function in packet-smb.c in the SMB dissector (CVE-2009-3551).

Impact

A remote attacker could entice a user to open a specially crafted “erf” file using Wireshark, possibly resulting in the execution of arbitrary code with the privileges of the user running the application. A remote attacker could furthermore send specially crafted packets on a network being monitored by Wireshark or entice a user to open a malformed packet trace file using Wireshark, possibly resulting in a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All Wireshark users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-1.2.3"
