Date: April 14, 2011

Affected versions: 1.2.0 up to and including 1.2.15

Fixed versions: 1.2.16



Wireshark 1.2.16 fixes the following vulnerability:

  • The X.509if dissector could crash. (Bug 5754, Bug 5793)
    Versions affected: 1.2.0 to 1.2.15 and 1.4.0 to 1.4.4.


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 1.2.16 or later.

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

  • Disable the X.509if dissector:
    • Select Analyze→Enabled Protocols... from the menu.
    • Make sure "X.509if" is un-checked.
    • Click "Save", then click "OK".
