[arch-general] CVE-2015-0235: glibc / heap overflow in gethostbyname()
by Ido Rosen 27 Jan '15

27 Jan '15

Hi Allan & others, This is a pretty big remote vulnerability, with a big attack surface. I'm not sure if this is the right list to be sending it to, but I'd suggest patching glibc right away. I think RedHat's already released an RHEL5 backported patch, and upstream has already patched it (as of yesterday). See the links below. Ido glibc bug report: https://sourceware.org/bugzilla/show_bug.cgi?id=15014 Upstream patch: https://sourceware.org/git/?p=glibc.git;a=commit;h=d5dd6189d506068ed11c8bfa… Debian bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=776391 RedHat bug: https://rhn.redhat.com/errata/RHSA-2015-0090.html Blog post describing the vulnerability: http://ma.ttias.be/critical-glibc-update-cve-2015-0235-gethostbyname-calls/ HN Discussion: https://news.ycombinator.com/item?id=8953545 Original report (afaict) in French: http://www.frsag.org/pipermail/frsag/2015-January/005722.html

Any ideas? sudo pacman -S python-virtualenv python2-virtualenv python-virtualenvwrapper Google how to use them. Actually virtualenv itself is enough. virtualenvwrapper is a useful wrapper, so I recommend to use them together. Here is my virtualenv and virtualenvwrapper configuration in .zshrc. You can take a look: # Python virtualenvwrapper export WORKON_HOME=$HOME/.virtualenvs #export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python2 if [ -f /usr/bin/virtualenvwrapper.sh ]; then source /usr/bin/virtualenvwrapper.sh fi # Python pip -> virtualenv only export PIP_REQUIRE_VIRTUALENV=true export PIP_RESPECT_VIRTUALENV=true ==================== YANG Ling yangling1984(a)gmail.com

[arch-general] Firefox stopped working
by Ralf Mardorf 24 Jan '15

24 Jan '15

Hi, I couldn't find a bugreport regarding firefox or glib from 2015 at https://bugs.archlinux.org/ or regarding glib at https://bugzilla.mozilla.org/ from 2015. IIRC Firefox still worked two days ago. Somebody else seeing the following? [rocketmouse@archlinux ~]$ firefox (process:29590): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed [rocketmouse@archlinux ~]$ grep firefox /var/log/pacman.log [snip] [2014-12-01 22:42] [PACMAN] upgraded firefox (33.1.1-1 -> 34.0.5-1) [2015-01-14 01:50] [ALPM] upgraded firefox (34.0.5-1 -> 35.0-1) [rocketmouse@archlinux ~]$ sudo pacman -S firefox [snip] [rocketmouse@archlinux ~]$ firefox (process:29691): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed [rocketmouse@archlinux ~]$ grep firefox /var/log/pacman.log [snip] [2015-01-24 16:09] [PACMAN] Running 'pacman -S firefox' [2015-01-24 16:09] [ALPM] reinstalled firefox (35.0-1) [rocketmouse@archlinux ~]$ grep glib /var/log/pacman.log [No entries for 2015] Firefox doesn't open. I don't have time for Gdb this weekend. I'll do it on Monday. Regards, Ralf

[arch-general] An archlinux-python package for managing system default python version?
by Chi Hsuan Yen 23 Jan '15

23 Jan '15

Dear Arch enthusiasts, The package extra/java-runtime-common provides a convenient script archlinux-java to handle co-existing JDK/JRE versions. I can use it to switch between different versions of java implementations to accomplish numerous tasks from testing the compatibilities of my programs to running third party applications targeting on different platforms. Now I hope there's also a simple script for the same thing but for python. On the system, most of the scripts are written for python2 and some other scripts are python3-specific. In most cases it's not a problem because I can fix the scripts or use some tricks like $PATH to ensure the correct execution of the programs. However, in large projects, doing either is time-consuming and costly. Recently I'm building CyanogenMod on Arch Linux. It includes lots of python scripts in the build system, and most of them requires python2. Using the tip provided on the article about Python on ArchWiki prevents lots of problems, but, however, some scripts have the shebang line "#!/usr/bin/env python" or are invoked by some command like "/usr/bin/python ...". I have to change the link /usr/bin/python to pointing to python2 for further progress on building and changed it back for my daily use. If there's an archlinux-python script, lots of time on battling the difference between python2 and python3 does not exist anymore, which I believe lots of users can benefit from it. Any ideas? Best Regards, Yen Chi Hsuan

[arch-general] lvm activation at boot
by Michael Dahlberg 20 Jan '15

20 Jan '15

I’m having a problem activating lvm volumes at boot. I have an lvm volume (/home) that is mounted at boot and listed in /etc/fstab. When I try and boot the system, activation of this logical volume times out and the system drops to single-user emergency shell. Once I login I can activate it (vgchange -ay) and mount it without any problems. I’ve run mkinitcpio several times, all with the mkinitcpio.conf file containing the following lines: MODULES=“dm_mod raid1” HOOKS=“base udev autodetect modconf block mdadm_udev lvm2 filesystems keyboard fsck” Any suggestions will be appreciated. -- Michael Dahlberg
