Bug ID 10470
Summary packet-gtpv2.c, trigging_tree under Trace information has wrong length
Product Wireshark
Version 1.12.0
Hardware x86-64
OS All
Status UNCONFIRMED
Severity Major
Priority Low
Component Dissection engine (libwireshark)
Assignee bugzilla-admin@wireshark.org
Reporter stavros.charos@nsn.com 

Build Information:
Version 1.12.0 
--
Based on 3GPP 32.422 technical specification, the size for triggering events
element under Trace information IE, is 9 bytes.
However in wireshark dissector packet-gtpv2.c, only 8 bytes has been defined
for triggering events (trigging_tree). As it seems subtree for 'PGW SGW'
sub-element (1 byte) is missing.
Due to this error the rest of the bytes of trace information IE are decoded
wrongly, giving also "Malformed Packet" indication.
