[CentOS] Boot Failed After 4.18.0-193.14.2.el8_2.x86_64

[Mark LaPierre]

Hey All,

My CentOS 8 system will not boot into the new kernel that was part of 
the update this evening.


How do I boot the previous kernel?  I can't select it on the boot menu. 
The only choice I can select, other than the new kernel that dies with a 
kernel panic, is the rescue kernel.


If I try to edit the boot command every time I touch the cursor key the 
cursor jumps 15 characters.


What now brown cow?

[CentOS] Centos 8: removing font rpms leaves directory and .uuid file behind

[Frank Cox]

remove an unneeded font that was installed during the initial setup:

dnf remove thai-scalable

ls -a /usr/share/fonts/thai-scalable

Not only did the directory survive the removal, but we still have a hidden file 
named .uuid in the directory (which is probably why it didn't get removed).

The directory and .uuid file is an orphan though, since rpm --whatprovides 
tells me that no rpm owns it.  Again, not surprising since we removed the rpm.

This happens when removing any of the default fonts like smc, any of the sil-* 
fonts and so forth.  They all leave their directory under /usr/share/fonts and 
a .uuid file behind.

Can we uninstall 2020 and install it again? This one has a virus.

Hi folks,

However, after login, when I do a DNF update (which is updating the kernel

end up on a blank screen. Tried fixing grub2 via recovery method, no luck.

Tried this couple of times, i.e, fresh install then dnf update, always
ended up with the same result.

In my latest reinstall, I did not format the boot and EFI partition, and
after it came up post the reinstall, I could see the upgraded kernel entry
from the last install in the grub menu.

Thoughts on what could be causing this and how could I fix it?

[CentOS] OpenJDK vulnerability and best way to find status of package that remediates vulnerability for CentOS

[Boushy, Phillip]

I have a docker image based off centos:7 with java-11-openjdk-devel.

It appears that the current java-11-openjdk-devel available in the CentOS 7 Yum 
repo is 1:11.0.7.10-4.el7_8

11.0.7 is reported to have some high vulnerabilities  RHSA-2020:2969 that are 
fixed in 11.0.8, but 11.0.8 is not available for CentOS 7.

1. Is there a 11.0.8 update for java-11-openjdk-devel available for CentOS 7?
2. Is there a page like Ubuntu's CVE Tracker site where it shows the CVE, the 
package name, and the status (e.g. 
https://people.canonical.com/~ubuntu-security/cve/2020/CVE-2020-14578.html)
3. If 2 is no, How can I look up the status of a package that has been released 
by upstream on CentOS? (e.g. it's been released in Upstream, it's available in 
CentOS, it's pending backport for CentOS 7)

Hole vulnerability
Message-ID: <0f0d3ad8-7160-73b7-82d2-6d8ff51ef...@centosproject.org>
Content-Type: text/plain; charset=utf-8

We are aware of the Boot Hole vulnerability in grub2 (CVE-2020-1073) and
are working on releasing new packages for CentOS Linux 7, CentOS Linux 8
and CentOS Stream in response. These should make it out to a mirror near
you shortly.


/!\ Secureboot Systems - Please do a full update /!\


CentOS Linux 8 and CentOS Stream systems with secureboot enabled MUST
update the kernel, grub2, and shim packages together. As part of this
CVE, we have re-issued the kernel and shim signing certificate
authorities, and previously released EL8 kernels cannot boot in
secureboot mode with the newer shim/grub2.


The following packages boot together in secureboot mode on CentOS Stream:

  *

kernel-4.18.0-227.el8 / kernel-rt-4.18.0-227.rt7.39.el8

  *

grub2-2.02-87.el8_2

  *

shim-x64-15-13.el8


The following packages boot together in secureboot mode on CentOS Linux 8:

  *

kernel-4.18.0-193.14.2.el8_2

  *

grub2-2.02-87.el8_2

  *

shim-x64-15-13.el8


For systems with CentOS Linux 7 or with secureboot disabled, we strongly
recommend doing a full `dnf/yum update` to pick up all of the latest
patches at the same time.

On behalf of the CentOS Team,

This is a minor correction to the CVE number referenced in this earlier
post.

CVE-2020-10713 is the correct assignment.

This is a link to the research article:
https://eclypsium.com/2020/07/29/theres-a-hole-in-the-boot/

Hello

The client architecture has nothing to see with server. Said that, if
you need the conector for 32 bit, try with the one in
https://dev.mysql.com/downloads/connector/odbc/ under RHEL/Oracle Linux.
It **should** work.

Good luck

If you can find the RPMS, you could rebuild for I686.

Hi all,

I am looking for a i686 package (32 bit) for mysql-connector-odbc. However, I 
could locate only the x86-64 version on the repositories. Not much of a DB 
person but trying to connect to a 64bit MySQL server on remote host.

Any suggestions where I can locate the i686 package? Is there a mariadb package 
that I can use?

Thanks.
