Thanks for reporting this.
Do you know how to reproduce this crash?

I've since upgraded to openssh-5.9p1-29.fc17.x86_64 and the crashed happened again today.

Unfortunately, I don't know what is the culprit that triggers this.
Maybe it is related, maybe not, but both times it happened, I was using eduroam WiFi with a public IP address, whereas usually I'm behind some NAT (at work or at home). And today I had a Denyhosts report at about the same time as the crash report.

Comment 14 Michal Hlavinka 2013-03-26 16:41:51 UTC
This should not be related. Could you attach /var/log/messages and /var/log/secure from time of the crash? Check if the logs (especially the second one) does not contain password in plaintext and if it does, replace it with ***

thanks

Comment 15 Fedora End Of Life 2013-07-04 00:59:33 UTC
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. 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bug reports from releases that are no longer maintained.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 WONTFIX if it remains open with a Fedora 
'version' of '17'.

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 prior to Fedora 17's end of life.

Bug Reporter:  Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 17 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 to Fedora 17's end of life.

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.

Comment 16 Fedora End Of Life 2013-08-01 05:03:41 UTC
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
