Bug report - Slice bounds out of range in GTP parsing

[raefko]

Slice bounds out of range in GTP

We (@FuzzingLabs) found an error in your code:

go-gtp/gtpv0/message/header.go

Line 88 in bd9a676

if l < 11 {

This length verification should be l < 20

This fix is recommended for the rest of the function starting from this line:

go-gtp/gtpv0/message/header.go

Line 97 in bd9a676

h.TID = binary.BigEndian.Uint64(b[12:20])

Otherwise, a panic: runtime error: slice bounds out of range [:20] with capacity XX is triggered
