HIGH Summary
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.

NASL family Debian Local Security Checks NASL id DEBIAN_DLA-1634.NASL description Several issues in wireshark, a tool that captures and analyzes packets off the wire, have been found by different people. These are basically issues with length checks or invalid memory access in different dissectors. This could result in infinite loops or crashes by malicious packets.
