Subject: do not infloop on a query ending in %XY, for invalid hex X or Y
X-Git-Url: https://gitweb.ps.run/ps-cgit/commitdiff_plain/fc384b16fb9787380746000d3cea2d53fccc548e?hp=fc384b16fb9787380746000d3cea2d53fccc548e

do not infloop on a query ending in %XY, for invalid hex X or Y

When a query ends in say %gg, (or any invalid hex) e.g.,
http://git.gnome.org/browse/gdlmm/commit/?id=%gg
convert_query_hexchar calls memmove(txt, txt+3, 0), and then returns
txt-1, so the loop in http_parse_querystring never terminates.  The
solution is to make the memmove also copy the trailing NUL.
* html.c (convert_query_hexchar): Fix off-by-one error.
