-----BEGIN PGP SIGNED MESSAGE-----Hash: SHA1________________________________________________________________________ Mandrake Linux Security Update Advisory________________________________________________________________________Package name: dhcpAdvisory ID: MDKSA-2002:037Date: May 29th, 2002Affected versions: 7.2, 8.1, 8.2, Single Network Firewall 7.2________________________________________________________________________Problem Description: Fermin J. Serna discovered a problem in the dhcp server and client package from versions 3.0 to 3.0.1rc8, which are affected by a format string vulnerability that can be exploited remotely. By default, these versions of DHCP are compiled with the dns update feature enabled, which allows DHCP to update DNS records. The code that logs this update has an exploitable format string vulnerability; the update message can contain data provided by the attacker, such as a hostname. A successful exploitation could give the attacker elevated privileges equivalent to the user running the DHCP daemon, which is the user dhcpd in Mandrake Linux 8.x, but root in earlier versions.________________________________________________________________________References:http://www.cert.org/advisories/CA-2002-12.htmlhttp://www.ngsec.com/docs/advisories/NGSEC-2002-2.txt________________________________________________________________________Updated Packages: Linux-Mandrake 7.2: 63c96314fca7bc3b5588e5d79b0061af 7.2/RPMS/dhcp-3.0b2pl9-4.1mdk.i586.rpm c4daa6288d8a5ca3efbb8b670c2f892e 7.2/RPMS/dhcp-client-3.0b2pl9-4.1mdk.i586.rpm b768b4211c5b8f27e579a30b14c39de7 7.2/RPMS/dhcp-relay-3.0b2pl9-4.1mdk.i586.rpm f7fa458ea1dcff467f6a275f29c46c58 7.2/SRPMS/dhcp-3.0b2pl9-4.1mdk.src.rpm Mandrake Linux 8.1: 83e839b3daa8b5bc8b68b9c63416d1b1 8.1/RPMS/dhcp-client-3.0-0.rc12.2.1mdk.i586.rpm 5888a11c60ee5c7610b1dc253fb717bb 8.1/RPMS/dhcp-common-3.0-0.rc12.2.1mdk.i586.rpm d0e736f945d830fef51b66d706b1603e 8.1/RPMS/dhcp-devel-3.0-0.rc12.2.1mdk.i586.rpm 8c2882ea0f2949ce455043a7e2896275 8.1/RPMS/dhcp-relay-3.0-0.rc12.2.1mdk.i586.rpm 2e592364d1585c7035637190328ede78 8.1/RPMS/dhcp-server-3.0-0.rc12.2.1mdk.i586.rpm f66331a2d7b4e7c449f71c1a8f52419e 8.1/SRPMS/dhcp-3.0-0.rc12.2.1mdk.src.rpm Mandrake Linux 8.1/ia64: 752a9a7b2b6795d621a628e511245303 ia64/8.1/RPMS/dhcp-client-3.0-0.rc12.2.1mdk.ia64.rpm fe580cd77c3a81effd9a5763a047c608 ia64/8.1/RPMS/dhcp-common-3.0-0.rc12.2.1mdk.ia64.rpm 6982f91d163ebb868851cc06b879d8d1 ia64/8.1/RPMS/dhcp-devel-3.0-0.rc12.2.1mdk.ia64.rpm a9f6335bddbe0a6e05bb89994a1f5bad ia64/8.1/RPMS/dhcp-relay-3.0-0.rc12.2.1mdk.ia64.rpm e04122ee3308e71d6aeb5cb7fb0469b2 ia64/8.1/RPMS/dhcp-server-3.0-0.rc12.2.1mdk.ia64.rpm f66331a2d7b4e7c449f71c1a8f52419e ia64/8.1/SRPMS/dhcp-3.0-0.rc12.2.1mdk.src.rpm Mandrake Linux 8.2: 371df43752ff22e7fef14dcaba840cdd 8.2/RPMS/dhcp-client-3.0-1rc8.2.1mdk.i586.rpm a553a675f7846b76b3b59099694e60dc 8.2/RPMS/dhcp-common-3.0-1rc8.2.1mdk.i586.rpm 7ed0e9de3c5ba558c90803cf76be07d9 8.2/RPMS/dhcp-devel-3.0-1rc8.2.1mdk.i586.rpm 64692e67e6852dbe092ccafd9d3ed1cf 8.2/RPMS/dhcp-relay-3.0-1rc8.2.1mdk.i586.rpm 0b727afbe2661aa95f5b2683ab70daae 8.2/RPMS/dhcp-server-3.0-1rc8.2.1mdk.i586.rpm 468feef9cee73cf8b352cbdfbd1ec25f 8.2/SRPMS/dhcp-3.0-1rc8.2.1mdk.src.rpm Mandrake Linux 8.2/ppc: 24d7cc2f572e27a578aecd8405cb7d97 ppc/8.2/RPMS/dhcp-client-3.0-1rc8.2.1mdk.ppc.rpm 2487d99b2bb6369d84809204aef42983 ppc/8.2/RPMS/dhcp-common-3.0-1rc8.2.1mdk.ppc.rpm 5d668bffa23b215fb2d3db351fe93ce2 ppc/8.2/RPMS/dhcp-devel-3.0-1rc8.2.1mdk.ppc.rpm 48523da7eddd3853c91ad563c05eb576 ppc/8.2/RPMS/dhcp-relay-3.0-1rc8.2.1mdk.ppc.rpm 051c1cf277ea455d8a2459074c3bf181 ppc/8.2/RPMS/dhcp-server-3.0-1rc8.2.1mdk.ppc.rpm 468feef9cee73cf8b352cbdfbd1ec25f ppc/8.2/SRPMS/dhcp-3.0-1rc8.2.1mdk.src.rpm Single Network Firewall 7.2: 63c96314fca7bc3b5588e5d79b0061af snf7.2/RPMS/dhcp-3.0b2pl9-4.1mdk.i586.rpm c4daa6288d8a5ca3efbb8b670c2f892e snf7.2/RPMS/dhcp-client-3.0b2pl9-4.1mdk.i586.rpm b768b4211c5b8f27e579a30b14c39de7 snf7.2/RPMS/dhcp-relay-3.0b2pl9-4.1mdk.i586.rpm f7fa458ea1dcff467f6a275f29c46c58 snf7.2/SRPMS/dhcp-3.0b2pl9-4.1mdk.src.rpm________________________________________________________________________Bug IDs fixed (seehttps://qa.mandrakesoft.com for more information):________________________________________________________________________To upgrade automatically, use MandrakeUpdate.
