Mandriva Linux Security Advisory MDVSA-2009:312 http://www.mandriva.com/security/ _______________________________________________________________________ Package : dhcp Date : December 3, 2009 Affected: 2008.0 _______________________________________________________________________ Problem Description: A vulnerability has been found and corrected in ISC DHCP: Integer overflow in the ISC dhcpd 3.0.x before 3.0.7 and 3.1.x before 3.1.1; and the DHCP server in EMC VMware Workstation before 5.5.5 Build 56455 and 6.x before 6.0.1 Build 55017, Player before 1.0.5 Build 56455 and Player 2 before 2.0.1 Build 55017, ACE before 1.0.3 Build 54075 and ACE 2 before 2.0.1 Build 55017, and Server before 1.0.4 Build 56528; allows remote attackers to cause a denial of service (daemon crash) or execute arbitrary code via a malformed DHCP packet with a large dhcp-max-message-size that triggers a stack-based buffer overflow, related to servers configured to send many DHCP options to clients (CVE-2007-0062). Stack-based buffer overflow in the script_write_params method in client/dhclient.c in ISC DHCP dhclient 4.1 before 4.1.0p1, 4.0 before 4.0.1p1, 3.1 before 3.1.2p1, 3.0, and 2.0 allows remote DHCP servers to execute arbitrary code via a crafted subnet-mask option (CVE-2009-0692). ISC DHCP Server is vulnerable to a denial of service, caused by the improper handling of DHCP requests. If the host definitions are mixed using dhcp-client-identifier and hardware ethernet, a remote attacker could send specially-crafted DHCP requests to cause the server to stop responding (CVE-2009-1892). Packages for 2008.0 are being provided due to extended support for Corporate products. This update provides fixes for this vulnerability. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0062 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0692 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1892 _______________________________________________________________________ Updated Packages: Mandriva Linux 2008.0: 3081299715b66778098307681861d6d7 2008.0/i586/dhcp-client-3.0.7-0.1mdv2008.0.i586.rpm 65893c30e369cb54df581508c0a278ce 2008.0/i586/dhcp-common-3.0.7-0.1mdv2008.0.i586.rpm c7891651d44f4c66967789a594cb494f 2008.0/i586/dhcp-devel-3.0.7-0.1mdv2008.0.i586.rpm 6ddeab5add9a44c4c0d97fc98e98b48f 2008.0/i586/dhcp-doc-3.0.7-0.1mdv2008.0.i586.rpm 2c3e9e31d4c99a3622ce4c029ce7d5f9 2008.0/i586/dhcp-relay-3.0.7-0.1mdv2008.0.i586.rpm e9271dcc129000708f9537a5ad3a926f 2008.0/i586/dhcp-server-3.0.7-0.1mdv2008.0.i586.rpm 2a2e6cca8ab0d7c62e14aa19116ac860 2008.0/SRPMS/dhcp-3.0.7-0.1mdv2008.0.src.rpm Mandriva Linux 2008.0/X86_64: 137eaf194b2faa3a8de3b90453c47793 2008.0/x86_64/dhcp-client-3.0.7-0.1mdv2008.0.x86_64.rpm 79a273d98b5ef2f51c93c0f4d49ab82a 2008.0/x86_64/dhcp-common-3.0.7-0.1mdv2008.0.x86_64.rpm 4e1ca48b749ef04f4aff6dd6d9d34bde 2008.0/x86_64/dhcp-devel-3.0.7-0.1mdv2008.0.x86_64.rpm df97bbd0680f5b82417be5fb448a3493 2008.0/x86_64/dhcp-doc-3.0.7-0.1mdv2008.0.x86_64.rpm daa25b01f8fd36eeeedc2cb4c0e2c119 2008.0/x86_64/dhcp-relay-3.0.7-0.1mdv2008.0.x86_64.rpm 1d283afe24bb93f3c155a2b762e50988 2008.0/x86_64/dhcp-server-3.0.7-0.1mdv2008.0.x86_64.rpm 2a2e6cca8ab0d7c62e14aa19116ac860 2008.0/SRPMS/dhcp-3.0.7-0.1mdv2008.0.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
