These have been upgraded to Linux kernel version 2.4.23, which fixes a bug in the kernel's do_brk() function that could be exploited to gain root privileges. These updated kernels and modules should be installed by any sites running a 2.4 kernel earlier than 2.4.23. Linux 2.0 and 2.2 kernels are not vulnerable. More details about the Apache issue may be found in the Common Vulnerabilities and Exposures (CVE) database: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0961 Here are the details from the Slackware 9.1 ChangeLog: +--------------------------+ Mon Dec 1 21:36:30 PST 2003 patches/kernels/: Upgraded to Linux 2.4.23. This fixes a bug in the kernel's do_brk() function which a local user could exploit to gain root privileges. For more details, see: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0961 Sites should upgrade to the 2.4.23 kernel and kernel modules. After installing the new kernel, be sure to run 'lilo'.

Those are found in this directory: ftp://ftp.slackware.com/pub/slackware/slackware-9.1/patches/kernels/ ALSA has also been updated to 0.9.8 and compiled for 2.4.23. These packages will also be required to use the ALSA sound system: ftp://ftp.slackware.com/pub/slackware/slackware-9.1/patches/packages/alsa-driver-0.9.8-i486-1.tgz ftp://ftp.slackware.com/pub/slackware/slackware-9.1/patches/packages/alsa-lib-0.9.8-i486-1.tgz ftp://ftp.slackware.com/pub/slackware/slackware-9.1/patches/packages/alsa-oss-0.9.8-i486-1.tgz ftp://ftp.slackware.com/pub/slackware/slackware-9.1/patches/packages/alsa-utils-0.9.8-i486-1.tgz The XFS patched kernel requires different kernel modules.

After installing the kernel-ide package you will need to run lilo ('lilo' at a command prompt) or create a new system boot disk ('makebootdisk'), and reboot. If desired, a kernel from the kernels/ directory may be used instead. For example, to use the kernel in kernels/scsi.s/, you would copy it to the boot directory like this: cd kernels/scsi.s cp bzImage /boot/vmlinuz-scsi.s-2.4.23 Create a symbolic link: ln -sf /boot/vmlinuz-scsi.s-2.4.23 /boot/vmlinuz Then, run 'lilo' or create a new system boot disk and reboot. +-----+ Slackware Linux Security Team http://slackware.com/gpg-key security@slackware.com +------------------------------------------------------------------------+ | HOW TO REMOVE YOURSELF FROM THIS 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.
