-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [slackware-security] Slackware 14.2 kernel (SSA:2021-072-01) New kernel packages are available for Slackware 14.2 to fix security issues. Here are the details from the Slackware 14.2 ChangeLog: +--------------------------+ patches/packages/linux-4.4.261/*: Upgraded. These updates fix various bugs and security issues, including the recently announced iSCSI vulnerabilities allowing local privilege escalation. Be sure to upgrade your initrd after upgrading the kernel packages. If you use lilo to boot your machine, be sure lilo.conf points to the correct kernel and initrd and run lilo as root to update the bootloader. If you use elilo to boot your machine, you should run eliloconfig to copy the kernel and initrd to the EFI System Partition. For more information, see: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-27363 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-27364 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-27365 (* Security fix *) +--------------------------+ Where to find the new packages: +-----------------------------+ Thanks to the friendly folks at the OSU Open Source Lab (http://osuosl.org) for donating FTP and rsync hosting to the Slackware project! :-) Also see the "Get Slack" section on http://slackware.com for additional mirror sites near you.

For a 32-bit SMP machine, use this command (substitute the appropriate kernel version if you are not running Slackware 14.2): # /usr/share/mkinitrd/mkinitrd_command_generator.sh -k 4.4.261-smp | bash For a 64-bit machine, or a 32-bit uniprocessor machine, use this command (substitute the appropriate kernel version if you are not running Slackware 14.2): # /usr/share/mkinitrd/mkinitrd_command_generator.sh -k 4.4.261 | bash Please note that "uniprocessor" has to do with the kernel you are running, not with the CPU. Most systems should run the SMP kernel (if they can) regardless of the number of cores the CPU has. If you aren't sure which kernel you are running, run "uname -a". If you see SMP there, you are running the SMP kernel and should use the 4.4.261-smp version when running mkinitrd_command_generator. Note that this is only for 32-bit -- 64-bit systems should always use 4.4.261 as the version. If you are using lilo or elilo to boot the machine, you'll need to ensure that the machine is properly prepared before rebooting. If using LILO: By default, lilo.conf contains an image= line that references a symlink that always points to the correct kernel. No editing should be required unless your machine uses a custom lilo.conf. If that is the case, be sure that the image= line references the correct kernel file. Either way, you'll need to run "lilo" as root to reinstall the boot loader. If using elilo: Ensure that the /boot/vmlinuz symlink is pointing to the kernel you wish to use, and then run eliloconfig to update the EFI System Partition. +-----+ Slackware Linux Security Team http://slackware.com/gpg-key security@slackware.com +------------------------------------------------------------------------+ | To leave the slackware-security mailing list: | +------------------------------------------------------------------------+ | Send an email to majordomo@slackware.com with this text in the body of | | the email message: | | | | unsubscribe slackware-security | | | | You will get a confirmation message back containing instructions to | | complete the process.
