SquirrelMail 1.4.5, PHP 4.4.1.
Plain text messages that are encoded in iso-2022-jp
exhibit an error when translating URLs into anchor
links. If the next character following a URL is a
full-width, iso-2022-jp encoded space, the entire line
gets interpreted as the URL.
For example (I hope SF displays this correctly):
The first line contains a full-width, iso-2022-jp
encoded space after the trailing slash and in SM, ends
up entirely as the anchor link. The second line, that
is a regular iso-8859-1 encoded space, is correctly
parsed for the URL.
I believe this is an error in functions/url_parser.php
with the variable $url_parser_poss_ends.
