## Description

Array index error in the uri\_lookup function in the URI parser for neon
0.26.0 to 0.26.2, possibly only on 64-bit platforms, allows remote
malicious servers to cause a denial of service (crash) via a URI with
non-ASCII characters, which triggers a buffer under-read due to a type
conversion error that generates a negative index.
