Bug ID: 13017
   Summary: Lua dissector crashes on "string.format("%s",
tree.text)"
   Product: Wireshark
   Version: 2.2.1
  Hardware: x86-64
OS: Windows 7
Status: UNCONFIRMED
  Severity: Major
  Priority: Low
 Component: Dissection engine (libwireshark)

It seems that using string.format with contents of TreeItem.text causes a
memory access violation. 

HOW TO REPRODUCE

1. Add this Lua dissector to Wireshark:
local proto = Proto("proto", "Protocol")
function proto.dissector(buffer, pinfo, tree)
string.format("%s", tree.text)
end
local udp_table = DissectorTable.get("udp.port")
udp_table:add(12345, proto)

2. Start listening on arbitrary interface and send an UDP packet through it,
with destination port = 12345.

3. Wireshark will print following message on the console:
01:51:03  Warn Dissector bug, protocol PROTO, in packet 16:
STATUS_ACCESS_VIOLATION: dissector accessed an invalid memory address

ADDITIONAL INFO
The crash happens only when "string.format("%s", tree.text)" is present in the
code. Additionally, changing "tree.text" to anything else fixes the crash.

[Wireshark-bugs] [Bug 12067] Unable to resize the packet list pane, packet details pane

[bugzilla-daemon]

https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=12067

--- Comment #18 from Eric Blanding  ---
I just found a workaround that may help point to the bug; the Packet Bytes pane
appears to be forcing the window wider to show a large number of individual
Bitstring tabs.

After I uncheck View --> Packet Bytes, I can manually drag the window to a
narrower size so it all fits on screen.  The checkmark returns after quit the
app and reopening the same file, which appears to be a separate bug.  The
window re-expands after applying the check under View --> Packet Bytes.

--- Comment #17 from Eric Blanding  ---
I was looking for solutions and found this bug.  My observation is the same as
James Elliot describes: the main window opens twice as wide as my actual
screen.

I have seen this with various pcap files, and do not have the ability to debug,
but I can reproduce this every time with at least one pcap at this point.  The
window size expands beyond the screen size after applying a filter for x2ap.  I
tried exporting only one packet from the original pcap to a new file. 
Filtering for x2ap on the new file containing a single packet does not resize
the window, so pcap file size or specific packet contents appear to be a
factor.  Removing the filter does not allow me to manually shrink the window
narrower, but I can still stretch it wider - i.e. some minimum window size
appears to be applied.

File size: 6.7MB
Protocols in the pcap:
Frame
Ethernet
802.1Q Virtual LAN
Internet Protocol Version 4
Stream Control Transmission Protocol
S1 Application Protocol
Malformed Packet
EUTRAN X2 Application Protocol (X2AP)
Unreassembled Fragmented Packet
Malformed Packet

Here is my info from the about box - I downloaded the installer from
