MEDIUM 5.5EPSS 1.44%

Does this matter?

Lower severity and a low EPSS score (1.44%). Track it; it rarely justifies an emergency change on its own.

Description

In Wireshark 2.6.0 to 2.6.5 and 2.4.0 to 2.4.11, the P_MUL dissector could crash. This was addressed in epan/dissectors/packet-p_mul.c by rejecting the invalid sequence number of zero.
