Soon after release of 2.0.0.10 version 2.0.0.11 is released:

This release corrects a problem that was found in the previous release, Firefox 2.0.0.10.

Update of the update:

The 2.0.0.8 release fixed some 200 issues, but accidentally regressed a few things. Most users won’t see any difference or experience any problems, and those 200 fixes make the 2.0.0.8 update very valuable, but you should never have to choose functionality over security. So we’re working fast to understand and fix these problems, and will shortly be issuing a 2.0.0.9 update to address them. The specific problems are:

• Bug 400406 – Firefox will ignore the “clear” CSS property when used beneath a box that is using the “float” property. There is a temporary workaround JS/CSS code available for web developers with affected layouts.
• Bug 400467 – Windows Vista users will get “Java not found” or “Java not working” errors when trying to load Java applets after updating. To fix this, users can right-click the Firefox icon and “Run as administrator”, then browse to a page with a Java applet — doing this once will fix the problem and permanently restore Java functionality.
• Bug 396695 – Add-ons are disabled after updating. Users can fix this problem by opening their profile folder and removing three files (extensions.rdf, extensions.ini and extensions.cache)
• Bug 400421 – Removing a single area element from an image map will cause the entire map to disappear. There is no workaround available at this time.
• Bug 400735 – Some Windows users may experience crashes at startup. There is no workaround available at this time.

Few hours after Adobe released patch for Acrobat reader exploit was released.

Currently you may receive e-mail with YOUR_BILL.pdf or INVOICE.pdf as attachment. When user opens file Trojan horse is installed to the system.

It is HIGHLY recommended to update to Acrobat reader 8.1.1.

How?

Launch acrobat and go to help –> check for updates.

Mozilla foundation updated Firefox to 2..0.0.7.

There are no new features – this is completely security fix release.

This one fixes only one MFSA 2007-28 “Code execution via QuickTime Media-link files” with critical impact.

It is recommended to do the update.

I use wine from rpmforge repository.

It works well, but all system (bitmap) fonts are missing. DAG could not confirm this as bug, but several other CentOS users confirm that this problem exists.

How to fix:

Install wine (You need rpmforge repo enabled)

yum install wine

Install msttcorefonts

Follow these instructions

move /usr/share/wine/fonts to fonts.old (if already exist remove c:\windows\fonts folder too)

cd /usr/share/wine

mv fonts fonts.old

It is done.

You can use wine and all fonts appear.

Recently site http://apt.sw.be/redhat/el5/en/mirrors-rpmforge went down and this broke my YUM. Here is the error:

Setting up repositories
Could not retrieve mirrorlist http://apt.sw.be/redhat/el5/en/mirrors-rpmforge error was
[Errno 4] IOError: <urlopen error (-2, 'Name or service not known')>
Error: Cannot find a valid baseurl for repo: rpmforge

As a solution I’ve edited manually my /etc/yum.repos.d/mirrors-rpmforge

vi /etc/yum.repos.d/mirrors-rpmforge

And commented out problem site.

Then edited /etc/yum.repos.d/rpmforge.repo

vi /etc/yum.repos.d/rpmforge.repo

And commented live list and uncommented file. Like this

#mirrorlist = http://apt.sw.be/redhat/el5/en/mirrors-rpmforge
mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge

Now YUM it is back. Still get some mirroring errors, but at least I can use it.

Since a lot of people work in runlevel 3 the previous tip may not work.

So I’ve searched for other solutions found another way of disabling system beep (on tab completion).

Just edit /etc/inputrc

vi /etc/inputrc

and uncomment following line:

# do not bell on tab-completion
set bell-style none

Then after next login system beep on tab completion will be disabled system-wide.

And another one:

as root type:

rmmod pcspkr

This one will remove the module responsible for playing sound on system speaker.

Adding

blacklist pcspkr
in /etc/modprobe.d/blacklist

Should disable the module too, but it is not working for me under CentOS 5 – submitted as bug.

Another one (Hardware):

If you have PC simply open the case and unplug speaker cable from the motherboard.

NOTE: PC speaker could be very usefull when troubleshooting problems so this option is not really recommended.

OR search in your BIOS for option to disable it.

Part I

After hacker released to the public details about Firefox URI flaw Mozilla released new version of Firefox – 2.0.0.6 with following security issues fixed:

1. Unescaped URIs passed to external programs
2. Privilege escalation through chrome-loaded about:blank windows

First critical and second with moderate impact. Both connected with how Mozilla handle URI protocol.

Time to update again.

Today I’ve accidentally locked myself with Linux screensaver.

How this happened?

I use English letters for my password, but when I’ve stepped back from my Linux workstation my keyboard group was with group different than English.

As result when I come back and tried to unlock myself I couldn’t enter the correct password.

Solutions:

1. First and simplest solution will be to kill X with Crtl+Alt+Backspace

2. Reboot the PC – Alt+Ctrl+Del

3. Try to fix it

Because I’ve had open and unsaved documents first 2 options will result loss of my work I’ve decided to go with third one.

How I did it:

A requirement is to have another PC and ssh access to main one.

1. Login via ssh to locked PC.

2. Start vnc server under your account

vncserver

Note you will need vnc server installed. How to do it is out of the scope – consult your documentation.

3. Open firewall ports required for VNC or simply shutdown firewall

/etc/init.d/iptables stop

4. On other PC start VNC client and connect to locked one

5. Start keyboard configuration

gnome-keyboard-properties

6. Remove all other layouts except English

7. Now you can return to locked PC and unlock it.

NOTE: This procedure was tested on LAN and CentOS 5.
