MEDIUM 5.5EPSS 1.40%
Does this matter?
Lower severity and a low EPSS score (1.40%). Track it; it rarely justifies an emergency change on its own.
Description
In Wireshark 2.6.0 to 2.6.4 and 2.4.0 to 2.4.10, the dissection engine could crash. This was addressed in epan/tvbuff_composite.c by preventing a heap-based buffer over-read.
