-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: dhclient < 2.0 Date: Tue Jul 11 15:12:22 CEST 2000 Affected SuSE versions: 6.1-6.4 Vulnerability Type: remote root compromise SuSE default package: no Other affected systems: all unix systems using this package ______________________________________________________________________________ A security hole was discovered in the package mentioned above. Please update it as soon as possible or disable the service if you are using this software on your SuSE Linux installation(s). Other Linux distributions or operating systems might be affected as well, please contact your vendor for information about this issue. Please note that we provide this information on an "as-is" basis only. There is no warranty whatsoever and no liability for any direct, indirect or incidental damage arising from this information or the installation of the update package. _____________________________________________________________________________ 1. Problem Description The client side program of the ISC DHCP package, dhclient, does not do quoting of server messages before passing them to /sbin/dhclient-script. This script is executed with root privileges. 2. Impact Dhclient could be tricked by a rogue DHCP server to execute commands as user root. This leads to a remote root compromise of the system using dhclient. 3. Solution Update the package from our FTP server. ______________________________________________________________________________ Please verify these md5 checksums of the updates before installing: (For SuSE 6.0, please use the 6.1 updates) AXP: 262677203e3b1dada23e65ae60d08264 ftp://ftp.suse.com/pub/suse/axp/update/6.3/n1/dhclient-2.0pl2-3.alpha.rpm 910097426b5771c82abf8f323086b5ba ftp://ftp.suse.com/pub/suse/axp/update/6.4/n1/dhclient-2.0pl2-3.alpha.rpm i386: 300a7c8220d3b9f65a2aef3ed4fdb7b3 ftp://ftp.suse.com/pub/suse/i386/update/6.1/n1/dhclient-2.0pl2-3.i386.rpm 7be68cd54e7fd3766b7eb36fc2e854c5 ftp://ftp.suse.com/pub/suse/i386/update/6.2/n1/dhclient-2.0pl2-3.i386.rpm 44fad0cee0cb53627ed7c507077d5d2b ftp://ftp.suse.com/pub/suse/i386/update/6.3/n1/dhclient-2.0pl2-3.i386.rpm 320d4414841e29bd08584fc5d8592d99 ftp://ftp.suse.com/pub/suse/i386/update/6.4/n1/dhclient-2.0pl2-3.i386.rpm PPC: a8a19501e4821ab6c7b375972eb1e5ce ftp://ftp.suse.com/pub/suse/ppc/update/6.3/n1/dhclient-2.0pl2-3.ppc.rpm b4ea052ba25b10586cc14f6fea5b2d9f ftp://ftp.suse.com/pub/suse/ppc/update/6.4/n1/dhclient-2.0pl2-3.ppc.rpm ______________________________________________________________________________ You can find updates on our ftp-Server: ftp://ftp.suse.com/pub/suse/i386/update for Intel processors ftp://ftp.suse.com/pub/suse/axp/update for Alpha processors or try the following web pages for a list of mirrors: http://www.suse.de/ftp.html http://www.suse.com/ftp_new.html Our webpage for patches: http://www.suse.de/patches/index.html Our webpage for security announcements: http://www.suse.de/security If you want to report vulnerabilities, please contact security@suse.de ______________________________________________________________________________ SuSE has got two free security mailing list services to which any interested party may subscribe: suse-security@suse.com - moderated and for general/linux/SuSE security discussions.
