Description Filip Krska 2014-06-26 13:59:22 UTC
mailx-12.5-10.fc20.x86_64 reproduces as well

+++ This bug was initially created as a clone of Bug #1113611 +++

mailx-12.5-11.el7.x86_64 reproduces as well

+++ This bug was initially created as a clone of Bug #1113592 +++

Description of problem:

mailx segfaults if

set from=

or e.g.

set from= some.put.after.a.space.com

line is present in /etc/mail.rc


Version-Release number of selected component (if applicable):

mailx-12.4-7.el6.x86_64

How reproducible:

Always

Steps to Reproduce:
1. put lines
set smtp=smtp.redhat.com
set from=

to /etc/mail.rc

2. run
# mailx -s Test fkrska
3.

Actual results:
b
.
EOT
Segmentation fault


Expected results:
b
.
EOT

mail sent

Additional info:

Patch proposed (mailx silently sends email with From: MAILER-DAEMON). Perhaps even more desired behavior would be to detect empty "from" (which has no use case and often caused by user mistakenly put space after "=") and print warning on stderr.

Comment 3 Dmitry Butskoy 2014-08-02 13:26:52 UTC
The actual upstream for mailx is
http://heirloom.sourceforge.net/mailx.html
(or see nail.sf.net for more info).

Comment 4 Jan Chaloupka 2014-08-04 05:35:31 UTC
Thank you Dmitry. I found this link but without mailing list.

From http://heirloom.sourceforge.net/mailx.html:

Mailx development is discussed on the nail-devel mailing list. All people interested in discussing or coding features for future releases are invited to participate. Bug reports should also be sent to the list. To subscribe to the list or look at the archives, visit <https://lists.sourceforge.net/lists/listinfo/nail-devel>. Currently, only subscribers are allowed to post.

Comment 5 Fedora End Of Life 2015-05-29 12:13:45 UTC
This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '20'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 20 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.
