-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [slackware-security] kernel security updates (SSA:2004-119-01) New kernel packages are available for Slackware 9.1 and -current to fix security issues. Also available are new kernel modules packages (including alsa-driver), and a new version of the hotplug package for Slackware 9.1 containing some fixes for using 2.4.26 (and 2.6.x) kernel modules. The most serious of the fixed issues is an overflow in ip_setsockopt(), which could allow a local attacker to gain root access, or to crash or reboot the machine. This bug affects 2.4 kernels from 2.4.22 - 2.4.25. Any sites running one of those kernel versions should upgrade right away. After installing the new kernel, be sure to run 'lilo'. More details about the issues may be found in the Common Vulnerabilities and Exposures (CVE) database: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0394 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0424 Here are the details from the Slackware 9.1 ChangeLog: +--------------------------+ Wed Apr 28 10:19:51 PDT 2004 patches/packages/kernel-ide-2.4.26-i486-2.tgz: The first version of this package included one of the old 2.4.22 kernels by mistake. Thanks to the many people who pointed out this error. Sorry! (* Security fix *) +--------------------------+ Tue Apr 27 15:25:29 PDT 2004 patches/packages/alsa-driver-0.9.8-i486-3.tgz: Recompiled for Linux 2.4.26. patches/packages/hotplug-2004_01_05-noarch-1.tgz: This adds bugfixes for using a 2.6.x kernel, and adds the broken via-ircc module to the hotplug blacklist. Note that upgrading the package will not replace an existing blacklist, but as far as I can tell there are no ill effects from trying to load via-ircc other than the ugly mess on the screen at boot time. patches/packages/kernel-ide-2.4.26-i486-1.tgz: Upgraded to Linux 2.4.26. patches/packages/kernel-headers-2.4.26-i386-1.tgz: Upgraded to Linux 2.4.26. patches/packages/kernel-modules-2.4.26-i486-1.tgz: Upgraded to Linux 2.4.26. patches/packages/kernel-source-2.4.26-noarch-1.tgz: Upgraded to Linux 2.4.26. patches/packages/kernels/*: Upgraded to Linux 2.4.26. These 2.4.26 kernel upgrades fix: an overflow in ip_setsockopt() [CAN-2004-0424] a flaw in do_fork() that could lead to a DoS an (unexploitable) overflow in panic() [CAN-2004-0394] For more details, see: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0394 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0424 (* Security fix *) WHERE TO FIND THE NEW PACKAGES: +-----------------------------+ Updated packages for Slackware 9.1: ftp://ftp.slackware.com/pub/slackware/slackware-9.1/patches/packages/alsa-driver-0.9.8-i486-3.tgz ftp://ftp.slackware.com/pub/slackware/slackware-9.1/patches/packages/hotplug-2004_01_05-noarch-1.tgz ftp://ftp.slackware.com/pub/slackware/slackware-9.1/patches/packages/kernel-ide-2.4.26-i486-2.tgz ftp://ftp.slackware.com/pub/slackware/slackware-9.1/patches/packages/kernel-headers-2.4.26-i386-1.tgz ftp://ftp.slackware.com/pub/slackware/slackware-9.1/patches/packages/kernel-modules-2.4.26-i486-1.tgz ftp://ftp.slackware.com/pub/slackware/slackware-9.1/patches/packages/kernel-source-2.4.26-noarch-1.tgz New precompiled kernels: ftp://ftp.slackware.com/pub/slackware/slackware-9.1/patches/kernels/ Updated packages for Slackware -current: ftp://ftp.slackware.com/pub/slackware/slackware-current/slackware/a/kernel-ide-2.4.26-i486-1.tgz ftp://ftp.slackware.com/pub/slackware/slackware-current/slackware/a/kernel-modules-2.4.26-i486-1.tgz ftp://ftp.slackware.com/pub/slackware/slackware-current/slackware/d/kernel-headers-2.4.26-i386-1.tgz ftp://ftp.slackware.com/pub/slackware/slackware-current/slackware/k/kernel-source-2.4.26-noarch-1.tgz ftp://ftp.slackware.com/pub/slackware/slackware-current/slackware/l/alsa-driver-1.0.4-i486-2.tgz New precompiled kernels: ftp://ftp.slackware.com/pub/slackware/slackware-current/kernels/ MD5 SIGNATURES: +-------------+ Slackware 9.1 packages: e628350bb01c18d7a6ad4706961601d8 alsa-driver-0.9.8-i486-3.tgz be986b3ebfd3a398990b249422707b84 hotplug-2004_01_05-noarch-1.tgz b45ba64a70f256ff33b35fb1ca409063 kernel-headers-2.4.26-i386-1.tgz a834060c508607169e98db7ede93409d kernel-ide-2.4.26-i486-2.tgz b34e78fa2b9f451007fa3a0849faedfe kernel-modules-2.4.26-i486-1.tgz ac3437a4ade365dce9b94afb3cb85d75 kernel-source-2.4.26-noarch-1.tgz Slackware -current packages: aa05198221027c6ce9055595ee76c409 kernel-ide-2.4.26-i486-1.tgz 1d2f8a04342dbf8482f67d9787a693c4 kernel-modules-2.4.26-i486-1.tgz 9e726b8766e807147cf4859a6bb33f48 kernel-headers-2.4.26-i386-1.tgz ac3437a4ade365dce9b94afb3cb85d75 kernel-source-2.4.26-noarch-1.tgz 3922b3ebba1029e0f1041dc6a1926bd2 alsa-driver-1.0.4-i486-2.tgz INSTALLATION INSTRUCTIONS: +------------------------+ Use upgradepkg to install the new packages. 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-2.4.26 Create a symbolic link: ln -sf /boot/vmlinuz-scsi.s-2.4.26 /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.
