Fedora Security :: What Is In Security Update?

Jan 5, 2010

I was reading that Arch does not provide security updates, but just provides security by keeping with up-to-date software...So what is in a security update and what does it patch? The kernel?

Fedora :: Cannot Login After Security Update

Sep 13, 2009

Yesterday, I updated my system with the latest security update and other software updates. Following the update, I am not able to log into the system after restart.As usual, I was prompted with the login page which looks as per normal. I chose my login id and entered my password. It brings me briefly to my desktop showing only my wallpaper (without any upper and bottom taskbars/panels). Then the screen went blank and the login page appeared again.I entered the login id and password, was shown the desktop wallpaper, screen went blank and the login page appeared. This continues over and over and over. After multiple tries and with some luck, I am able to log in as per normal.What seems to be the problem?

1. How do I check the system for errors?
2. How do I check which update has been updated?
3. Is there any way for me to restore to its original state (I migrated from FC10 to FC11 via yum update)?

The only other change apart from the security update is that I installed wine - which has been uninstalled the moment I was able to re-logged in.I attach the details of my grub.conf file below which I hope could be of some useful info.

Fedora :: Security Update Failed

Feb 3, 2010

I just installed FC12 and was trying to do the security update, but it encountered an "internal error" and asked me to "report this bug to the distribution's bugtracker" with the details. However, I am not sure exactly what to do. Could someone be kind enough to let me know?

Fedora Security :: Some Applications Won't Launch After Update (10)?

Mar 25, 2009

Today (25 of March) Fedora 10 asked to install latest security updates. I allowed it to install them and everything seemed ok. But after the next boot I understood that some applications won't launch. Skype, last.fm player, VirtualBox - all the qt ones. I've reinstalled those apps, and reinstalled qt. They still don't launch.When I execute one of them from terminal - it just waits and nothing happens.The process really starts, I can see it from ps -A and gnome's System Monitor.Here's the /var/log/yum.log for March 25th:

Mar 25 00:20:37 Updated: libX11-1.1.5-1.fc10.i386
Mar 25 00:20:39 Updated: lcms-libs-1.18-1.fc10.i386
Mar 25 00:20:44 Updated: gtk2-2.14.7-7.fc10.i386

Fedora Security :: Security Risk Of An Unencrypted /boot Partition?

Apr 8, 2009

During a recent install I made the leap to encryption,but /boot must remain unencrypted.Is there really any legitimate security risk to having an unencrypted /boot partition? I mean basically someone can just see what kernel you're running which they could see during boot anyways right? Oh I and keep all my financial documents in /boot/finances/ (haha ok not really, but I am serious about the first part).

Fedora Security :: SELinux - Update Stopped Printing

Mar 6, 2009

I know very little about SE Linux and I've heard that in some situations it's better to disable it. For a home user, is it important? Does it improve your life ? or does it get in the way ?

Last week some update stopped my printing and I had to install the new hplip from HP because it wasn't in the Fedora repos to correct the problem. I don't know if SELinux had anything to do with it, but today when I disabled SELinux a few minutes later I get a star up on the toolbar and when I clicked on it it mentioned something about hplip. It wouldn't make any sense to me but maybe this has happened to others.

Fedora Installation :: Computer Won't Boot After Security Update

Jul 21, 2010

Just finished a security update, (Fedora 12) and it said I had to restart the computer to have it take effect. When I restarted, all I got was the "Compaq" logo....forever. No Grub2 (it's a three system set up), no bios, just the brand name of the box. Even worse, when I tried going at it with a live cd, the same thing; the bios never loads, so no live cd fix.

Fedora :: Yum Dependency Checking Broken By Security Update?

Jun 22, 2011

The problem is that yum is refusing to install gcc on a new SL6 install. As far as I can make out, a security update that I applied prior to my attempt to install gcc has caused problems. I did a new SL6 install (x86_86) a couple of weeks ago. This was a minimal installation, and I didn't install any dev tools, as I intended to install them later from yum. Since then, I've done very little; I installed a few packages (samba, xemacs, etc), and I let the system update itself. The update installed 'kernel', and updated 'kernel-firmware' [URL]. I now need to install the dev tools (g++, and so on), but I can't. I've tried this from gpk-application, and directly from yum. The complete yum output is below, but the basic error is:

> Error: Package: glibc-2.12-1.7.el6.i686 (sl)
> Requires: glibc-common = 2.12-1.7.el6
> Installed: glibc-common-2.12-1.7.el6_0.5.x86_64 (@sl-security)

Fedora Security :: Remove Nagging Security Screen?

Oct 10, 2009

If I leave the computer running for a few minutes without doing anything on it, this screen appears demanding that I enter my password, otherwise I can't get back to Fedora. I understand the necessity for this security feature in a work environment, but I'm just a home user and this security screen is just a nagging problem I don't know how to get rid of.

Fedora Security :: Still No Security Patched Firefox 3.5.1 In Yum / Get That?

Jul 18, 2009

Firefox 3.5 has a critical java script vulnerability as noted in the recent news. I had to manually update to 3.5.1 using the mozilla tarball because there's still no Firefox 3.5.1 in Fedora Updates or even Fedora Updates Testing repositories. Is this normal? I didn't want to resort to using the mozilla one because now I can't use flash (my system is 64 bit and mozilla only seems to offer a 32bit tar file of Firefox) and having two Firefoxs means dealing with the ProfileManager, separate bookmarks and so on.

I'm trying to find out if I'm just looking in the wrong place, I tried the normal mirrors for "updates" for Fedora 11 and then updates-testing and also the baseurl for "updates" to get rid of the mirror update delay. None of them seem to have 3.5.1 ?

Fedora Security :: Backwards Security - Networking ?

Aug 3, 2009

Problem that may require several tools available on Fedora. I don't know if its possible or not.

Given: Surveillance video box based on Fedora & Zoneminder. Internet connection is via a private 10.x.x.x network connection to the local phone company/ISP. That's the only connection available and they are the only ISP in the area. The ISP uses NAT to ultimately provide a routeable IP address, but that only works on outbound initiated traffic.

Problem: How can someone out on the Internet hit this box? i.e Is there any way to rig a method that will ultimately allow a connection initiated from the Internet to see the surveillance video that this box has stored via an http session?

I thought of one idea but don't have the tools to implement it. User sends an email to a server out on the Net somewhere. Surveillance box retrieves mail ever minute. The mail contains the users IP address. Surveillance box sends an outbound packet to that IP address to get NAT functional. The users box then uses that address to hit the box on the private network. The snag with this is that NAT is specific to ports, and I have no sway over the ISP's NAT capability.

Is there any way to push an http session outbound to the waiting end user? i.e. initiate a push of http traffic from the private box to the end user?
