Wireshark is a program for monitoring network traffic. Wireshark was previously known as Ethereal.

Multiple buffer overflow flaws were found in the Wireshark SigComp Universal Decompressor Virtual Machine (UDVM) 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-2010-2287, CVE-2010-2995)

Several denial of service flaws were 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-2010-1455, CVE-2010-2283, CVE-2010-2284, CVE-2010-2286)

Users of Wireshark should upgrade to these updated packages, which contain Wireshark version 1.0.15, and resolve these issues. All running instances of Wireshark must be restarted for the update to take effect.

Several implementation errors in the dissector of the Wireshark network traffic analyzer for the ASN.1 BER protocol and in the SigComp Universal Decompressor Virtual Machine may lead to the execution of arbitrary code.

Wireshark version 1.4.2 fixes several security issues that allowed attackers to crash wireshark or potentially even execute arbitrary code
