Wireshark is a network protocol analyzer with a graphical front-end.
Multiple buffer overflows and infinite loops were discovered in multiple dissector and parser components, including those for MP3 and NCP (CVE-2007-6111), PPP (CVE-2007-6112), DNP (CVE-2007-6113), SSL and iSeries (OS/400) Communication traces (CVE-2007-6114), ANSI MAP (CVE-2007-6115), Firebird/Interbase (CVE-2007-6116), HTTP (CVE-2007-6117), MEGACO (CVE-2007-6118), DCP ETSI (CVE-2007-6119), Bluetooth SDP (CVE-2007-6120), RPC Portmap (CVE-2007-6121), SMB (CVE-2007-6438), IPv6 amd USB (CVE-2007-6439), WiMAX (CVE-2007-6441), RPL (CVE-2007-6450), CIP (CVE-2007-6451). The vulnerabilities were discovered by Stefan Esser, Beyond Security, Fabiodds, Peter Leeming, Steve and ainsley.
A remote attacker could send specially crafted packets on a network being monitored with Wireshark or entice a user to open a specially crafted file, possibly resulting in the execution of arbitrary code with the privileges of the user running Wireshark (which might be the root user), or a Denial of Service.
There is no known workaround at this time.
All Wireshark users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-0.99.7"
