The following vulnerabilities were discovered in the Squeeze’s Wireshark
version:
Since back-porting upstream patches to 1.2.11-6+squeeze15 did not fix
all the outstanding issues and some issues are not even tracked publicly
the LTS Team decided to sync squeeze-lts’s wireshark package with
wheezy-security to provide the best possible security support.
Note that upgrading Wireshark from 1.2.x to 1.8.x introduces
several backward-incompatible changes in package structure, shared
library API/ABI, availability of dissectors and in syntax of command
line parameters.
