fetchmail mimedecode option drops last message line if unterminated

[Axel G. Rossberg]

Over the last year or so (perhaps since update to fetchmail 6.3.21), I had a problem that in messages sent from one particular mail server (Microsoft Exchange) the messages I recieved had no text in the body at all.

I then found that for plain text messages that are not terminated with a newline (sent using the ms webmail interface) the last line of the message gets lost. I assume that HTML messages are sent as a single, unterminated line, and therefore get entirely lost.

The problem disappeared (at least that for plain text messages) when turning the mimedecode option off under fetchmail.

Ubunutu release: 12.04

Confirmed by upstream maintainer (yours truly), to be fixed in 6.3.26 (not yet released).

[Matthias Andree (matthias-andree)]

I have just released fetchmail 6.3.26 to fix this bug.

This should be made "High" priority as it causes data corruption for some users.

This should be marked "triage".

A patch is available from the upstream Git repo:
http://gitorious.org/fetchmail/fetchmail/commit/21ac960a3e648cd53c155bd2b724f72f0164416f?format=patch

[Matthias (matthias-redhat-bugs)]

Description of problem:
fetchmail loses the last line of a message (and thus possibly the entire message if it is HTML) if the mimedecode option is enabled and the last line is not properly terminated (CRLF/LF).

This is confirmed by the upstream author.

Version-Release number of selected component (if applicable):
Affects all upstream releases before 6.3.26 unless specifically patched.

How reproducible:

Note that the mimedecode option defaults to "off".

Trusty is carrying 6.3.26, so this issue affects Precise only, which reached EOL this past April.

[Steve Langasek (vorlon)]

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
