_ Sharp NetWalker PC-Z1 触って来た

近所の電気屋でSharp NetWalker PC-Z1を触って来た。個人的には、

• キーボードの感触が酷い。グラグラしつつ押し込みが硬い。
• マイク(端子)が無い。ICレコーダとして使えない(今現在SL-6000Dを、その用途で利用してるので、出来れば同じように使いたい)。

今回は見送りかなと。次期(が有れば)機種に期待しようかと。

_ Ximageon on ARMedslack with SL-C860でVGA, QVGAの切替え

_ CVE-2014-6271: remote code execution through bash

BASH PATCH REPORT bash43-025

Before version up

$ env x='() { :;}; echo vulnerable' bash -c "echo this is a test"
vulnerable
this is a test

OMG!

Let's do version up to bash-4.3.25 on Slackware.

$ tar xvvf bash-4.3.tar.gz
$ tar xvvf bash-4.3-patches.tar.gz
$ cd bash-4.3
$ cat ../bash-4.3-patches/bash43* | patch -p0
$ ./configure --prefix=/usr --mandir=/usr/man --infodir=/usr/info
$ make

# make install-strip

# cd /usr/bin
# mv bashbug bashbug.REMOVED && chmod -x bashbug.REMOVED
# mv bash /bin/bash.new
# ln -sf /bin/bash .

# cd /bin
# mv bash bash.old
# mv bash.new bash
# mv bash.old bash.old.REMOVED && chmod -x bash.old.REMOVED

After version up

$ env x='() { :;}; echo vulnerable' bash -c "echo this is a test"
bash: warning: x: ignoring function definition attempt
bash: error importing function definition for `x'
this is a test

But CVE-2014-7169 is not fixed yet :(

I noticed that libicui18n.a was built from *.ao in first build, but libicui18n.a was built from *.o in second build. I have never seen such ".ao" extention for object and I couldn't understand why libicui18n.a was built in different way in first and second build.

Third build succeeded :D

I continue to build again and it succeeded. I feel it very strange.

I tried to fix about build issue(1)

I think this issue may be related to "parallel make function" of gnu-make, so I changed .mozconfig to something like:

export LDFLAGS="-latomic"
. $topsrcdir/browser/config/mozconfig
ac_add_options --enable-optimize
ac_add_options --enable-default-toolkit=cairo-gtk2
ac_add_options --disable-debug
ac_add_options --disable-tests
ac_add_options --disable-mochitest
ac_add_options --enable-gstreamer=1.0
mk_add_options MOZ_MAKE_FLAGS=-j1

With this .mozconfig, first build failed but second build succeeded.

I tried to fix about build issue(2) RESOLVED!

I have no doubt that some thing issue about "parallel make function" causes to fail build, so I got sources of gnu-make and patch which include fix for "parallel make function" from Slackware-current and built it to replace old gnu-make. After that, build of firefox succeeded in first time with even first .mozconfig without "mk_add_options MOZ_MAKE_FLAGS=-j1" option :)
