Wireshark 1.2.14 fixes the following vulnerabilities:

  • FRAsse discovered that the MAC-LTE dissector could overflow a buffer. (Bug 5530) Versions affected: 1.2.0 to 1.2.13 and 1.4.0 to 1.4.2. CVE-2011-0444
  • FRAsse discovered that the ENTTEC dissector could overflow a buffer. (Bug 5539) Versions affected: 1.2.0 to 1.2.13 and 1.4.0 to 1.4.2. CVE-2010-4538


It may be possible to make Wireshark crash by injecting a series of malformed packets onto the wire or by convincing someone to read a malformed packet trace file.


Upgrade to Wireshark 1.2.14 or later.

If are running Wireshark 1.2.13 or earlier (including Ethereal) and cannot upgrade, you can work around each of the problems listed above by doing the following:

  • Disable the ENTTEC and MAC-LTE dissectors:
    • Select Analyze→Enabled Protocols... from the menu.
    • Make sure "ENTTEC" and "MAC-LTE" are un-checked.
    • Click "Save", then click "OK".
