Roundcube does not show emails
by Nicolas Kovacs 09 Dec '19

09 Dec '19

Hi, I installed Roundcube 1.4.1 on a sandbox server running CentOS 7, Postfix and Dovecot, with half a dozen test email accounts. Mail is setup correctly under the hood, e. g. I can access any account via Thunderbird for sending and receiving mail. And SELinux is set to permissive until everything works correctly. I took some notes (in french) on the installation procedure under CentOS : * https://github.com/kikinovak/HOWTOs/blob/master/Roundcube-HOWTO.txt All tests in the installer (including SMTP and IMAP login) are OK. But still, when I login to an account, no emails are showing. The inbox shows up empty, even if it's not. Another malfunction is that I cannot edit any identity. When I click on the user's identity, I get a spinning wheel, and the page does not open. I already have Roundcube 1.4rc1 running on my main workhorse server, it runs nicely. I tried to figure out what I did differently on that machine, but couldn't figure it out so far. I took a peek in the various log files, but found nothing suspect. Or maybe I don't know what to look for. Any suggestions? I'm a bit clueless here and don't even know where to start.

Updating firefox after a long time yum-excluded it and having installed it from .rpm
by wwp 08 Dec '19

08 Dec '19

Hello, I've been stuck for a while with an old version of firefox, installed from local .rpm (I know.. I should have downgraded using yum, instead) and added a exclude=firefox to the relevant .repo file. I did that after a yum-update has brought firefox 52+, and all add-ons were deprecated because of their new add-on scheme. Today that all the add-ons I need are available, I've tried upgrading to the latest Firefox version available from the updates repo.. I removed the exclude line in .repo file, but `yum update` didn't bring any firefox version at all: "No packages marked for update". I've struggled a bit, no way to get firefox installed using yum. See.. $ rpm -q firefox firefox-52.8.0-1.el7.centos.x86_64 $ yum info firefox Installed Packages Name : firefox Arch : x86_64 Version : 52.8.0 Release : 1.el7.centos Size : 149 M Repo : installed From repo : /firefox-52.8.0-1.el7.centos.x86_64 [snip] $ yum search firefox firefox.x86_64 : Mozilla Firefox Web browser $ yum update firefox No packages marked for update $ rpm -q firefox firefox-52.8.0-1.el7.centos.x86_64 $ rpm -e firefox $ rpm -q firefox package firefox is not installed $ yum install firefox No package firefox available. Even: $ yum localinstall firefox-68.2.0-1.el7.centos.x86_64.rpm Examining firefox-68.2.0-1.el7.centos.x86_64.rpm: firefox-68.2.0-1.el7.centos.x86_64 Nothing to do I still can install it using `rpm -i`, but I'm afraid yum-updates will not bring anything later. What an I doing wrong? Regards, -- wwp https://useplaintext.email/

Re: [CentOS] VPN connections subject to hijack attack

However, they found ipv6 works without rp_filter so this is a problem. But guess what it gets worse .. every Unix and semi Unix OS seem vulnerable.. from the email: We have discovered a vulnerability in Linux, FreeBSD, OpenBSD, MacOS, iOS, and Android which allows a malicious access point, or an adjacent user, to determine if a connected user is using a VPN, make positive inferences about the websites they are visiting, and determine the correct sequence and acknowledgement numbers in use, allowing the bad actor to inject data into the TCP stream. This provides everything that is needed for an attacker to hijack active connections inside the VPN tunnel. Now if 2 is needed for anything like docker/containers/etc then people are going to be royally screwed. > Technical details: > > <https://seclists.org/oss-sec/2019/q4/122> > > According to the report, systemd changed the default to 2 in November 2018 > so many distros are vulnerable. > > Here's Red Hat's explanation of why you might want to use a value of 2. > "When RHEL has multiple IPs configured, only one is reachable from a remote > network.

Failed to load SELinux policy- freezing
by Bill Gee 06 Dec '19

06 Dec '19

This is annoying! I have a CentOS7 virtual machine running on VirtualBox. Short version: At boot the system locks with a message: "Failed to load SELinux policy, freezing." VirtualBox thinks it is still running, and I can see it consuming a small amount of CPU time. But it never goes past this message. The problem actually started with a problem in the sound system on this virtual machine. It would boot a ways through, then abort with no warning and no message. It just went away. Looking at the VirtualBox log file, I saw that the last line in the file was something about failing to initialize a stream associated with PulseAudio. In VirtualBox settings for the machine I disabled all audio. It then booted. I was in the process of gathering information for a problem report at VB when it started giving the message about SELinux policy. There were several aborts including one where it almost got to loading the X server and going graphical. SELinux is disabled on the computer, so I don't understand why it is even trying to load a policy. Is there a kernel parameter I can give it to stop SELinux? Is there any other way to get past this message? -- Bill Gee

VPN connections subject to hijack attack
by Kenneth Porter 06 Dec '19

06 Dec '19

<https://www.bleepingcomputer.com/news/security/new-linux-vulnerability-lets…> This affects all VPNs and is a consequence of using "loose" reverse path filtering for anti-spoofing. The default CentOS setting is strict filtering but you may have changed this to loose for some unusual routing situations. Check that the value of /proc/sys/net/ipv4/conf/all/rp_filter is still set to 1. If it's set to 2 (loose filtering), you're vulnerable. Technical details: <https://seclists.org/oss-sec/2019/q4/122> According to the report, systemd changed the default to 2 in November 2018 so many distros are vulnerable. Here's Red Hat's explanation of why you might want to use a value of 2. "When RHEL has multiple IPs configured, only one is reachable from a remote network. Or why does RHEL ignore packets when the route for outbound traffic differs from the route of incoming traffic?" <https://access.redhat.com/solutions/53031>
