Description Vincent Danen 2014-01-29 19:55:42 UTC
These aren't security flaws, precisely, due to some of the other defaults that Fedora has that other distros/vendors may not, but upstream recently did some hardening to the defaults they provide (and we don't change) based on Martin Carpenter's report.

    e_sys - address security concerns with environment and gdb

    1. clear out environment as best is possible before executing
    anything. especially PATH and IFS are set to minimal base defaults.
    also use clearenv() if available and unsetenv()

    2. remove gdb method as it's just too dangerous. run it as normal as
    the user and if the kernel / distro dny that - then sorry. too bad.

Comment 1 Vincent Danen 2014-02-05 16:26:23 UTC
Just to note that these issues received two CVE names from MITRE [1]:

>  1. clear out environment as best is possible before executing
>     anything. especially PATH and IFS are set to minimal base defaults.
>     also use clearenv() if available and unsetenv()

Use CVE-2014-1845 for this issue in which the environment isn't
properly restricted.


> 2. remove gdb method as it's just too dangerous. run it as normal as
>    the user and if the kernel / distro dny that - then sorry. too bad.

Use CVE-2014-1846 for this issue in which gdb is available unsafely in
the unpatched codebase.

These issues do not affect Fedora in any significant way, so the filing of this bug is to include these as hardening (so as to prevent a user/admin from shooting their own foot) but not necessarily because we ship Fedora in a vulnerable way.

I'm adding the CVEs as aliases to this bug only because it makes it easy to find the bug due to the association, not because this affects Fedora as a security flaw.

Comment 2 Fedora End Of Life 2015-05-29 10:44:12 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bug reports from releases that are no longer maintained.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.

Comment 3 Fedora End Of Life 2015-06-29 14:52:02 UTC
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 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. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

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