CVE-2017-7746

In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the SLSK dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-slsk.c by adding checks for the remaining length.

Weakness

The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
