Wireshark is a network protocol analyzer with a graphical front-end.
Multiple unspecified errors exist in the SCTP, SNMP, and TFTP dissectors.
A remote attacker could cause a Denial of Service by sending a malformed packet.
Disable the SCTP, SNMP, and TFTP dissectors.
All Wireshark users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-0.99.8"
