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.

The installed version of Wireshark or Ethereal is potentially affected by multiple vulnerabilities. 

 - The SMB dissector can be affected by a NULL pointer    dereference. (Bug 4734)

 - The ANS.1 BER dissector can be affected by a buffer    overflow.

 - The SMB PIPE dissector can be affected by a NULL pointer    dereference on some platforms.

 - The SigComp Universal Decompressor Virtual Machine can    be affected by an infinite loop or a buffer overflow.
