Wrong charset regex in mime_decode.php

[weevsolutions]

Hi, the regex /charset=["\']?([^"\']*)/i' at line 297 matches 'iso-8859-15; format=flowed' instead of 'iso-8859-15'
I've replaced the regex with: "/charset=[\"|\']*([^\;|^\n|^\"|^\']*)[\"|\'|\;]*/i" and seems to work.

The bug causes body text truncation using special chars like € or à encoded in iso-8859

edit 19.29: updated regex

The bug is still present in 2.8.1.


Bug scenario:
If the charset is not the last parameter of Content-Type and if special characters are present in mail body the message is truncated.

Example of Content-Type:
Content-Type: text/plain; charset=iso-8859-15; format=flowed

Solution:
Replace the line 297 of ext/classes/mail/mime_decode.php with this:

Code: Select all

 if(preg_match('/charset=[\"|\']*([^\;|^\n|^\"|^\']*)[\"|\'|\;]*/i', $headers[$key]['value'], $matches))

Strange, I naver had issue like hits. But anyway I have done this modification. See attached.
This fix will be for 2.8.2

/charset=[\"\']*([^\;\n\"\']*)/i
