This is a security release fixing out-of-bounds reads when processing smart-protocol "ng" packets.
When parsing an "ng" packet, we keep track of both the current position as well as the remaining length of the packet itself. But instead of taking care not to exceed the length, we pass the current pointer's position to strchr, which will search for a certain character until hitting NUL. It is thus possible to create a crafted packet which doesn't contain a NUL byte to trigger an out-of-bounds read.
The issue was discovered by the oss-fuzz project, issue 9406.
