HAProxy - Load balancer

A bug during H1 data parsing may lead to copy more data than the maximum allowed. The bug is an overflow on this max threshold when it is lower than the size of an htx_blk structure. At first glance, it means it is possible to not respsect the buffer's reserve. So it may lead to rewrite errors but it may also block any progress on the stream if the compression is enabled. In this case, the channel buffer appears as full and the compression must wait for space to proceed. Outside of any bug, it is only possible when there are outgoing data to forward, so the compression filter just waits. Because of this bug, there is nothing to forward. The buffer is just full of input data. Thus nothing move and the stream is infinitly blocked. To fix the bug, we must be sure to be able to create an HTX block of 1 byte without exceeding the maximum allowed. This patch should fix the issue #2053. It must be backported as far as 2.5. |
