Summary

Wireshark is a program for monitoring network traffic. Wireshark was previously known as Ethereal.
A heap-based buffer overflow flaw was found in the Wireshark Local Download Sharing Service (LDSS) dissector. If Wireshark read a malformed packet off a network or opened a malicious dump file, it could crash or, possibly, execute arbitrary code as the user running Wireshark. (CVE-2010-4300)
A denial of service flaw was found in Wireshark. Wireshark could crash or stop responding if it read a malformed packet off a network, or opened a malicious dump file. (CVE-2010-3445)
Users of Wireshark should upgrade to these updated packages, which contain Wireshark version 1.2.13, and resolve these issues. All running instances of Wireshark must be restarted for the update to take effect.
