[SM-DEVEL] From line causes Apache server to crash.

[Daniel W. <da...@wi...>]

Hi all,

I had a nasty experience this weekend. My uncle (whose mail my server
carries) called and said that he could not read his mail via the webmail
(SquirrelMail 1.4.11). I logged in and lo, he was right!

After some investigation I noticed that his mailbox caused the Apache
server (2.2.6 [Debian 2.2.6-2]) to seg-fault!

Looking through the mail files on my IMAP server (Cyrus IMAP 2.3.7) I
found the mail that caused the problems. It was sent from Korea and
contained a "From" field in the headers that looks like this:

  From: =?euc-kr?q?=BD=C2=BF=EC=20=C8=B2?= <scu...@ya...>

If I changed this to something non-quoted, then everything works as it
should.

I've filed a bug report on this (1825492). I consider this to be a serious
bug as it not only prevented my uncle from reading his mail, but also
caused my web-server to crash.

Can someone please take a look at this?

Best regards
