| Description |
| An issue was discovered in HAProxy before 1.8.8. The incoming H2 frame
length was checked against the max_frame_size setting instead of being
checked against the bufsize. The max_frame_size only applies to
outgoing traffic and not to incoming, so if a large enough frame size
is advertised in the SETTINGS frame, a wrapped frame will be
defragmented into a temporary allocated buffer where the second
fragment may overflow the heap by up to 16 kB. It is very unlikely that
this can be exploited for code execution given that buffers are very
short lived and their addresses not realistically predictable in
production, but the likelihood of an immediate crash is absolutely
certain.
