Titel:	Mandriva Security Advisory MDVSA-2012:115 (dhcp)
Zusammenfassung:	NOSUMMARY
Beschreibung:	Description: The remote host is missing an update to dhcp announced via advisory MDVSA-2012:115. Multiple vulnerabilities has been discovered and corrected in ISC DHCP: An unexpected client identifier parameter can cause the ISC DHCP daemon to segmentation fault when running in DHCPv6 mode, resulting in a denial of service to further client requests. In order to exploit this condition, an attacker must be able to send requests to the DHCP server (CVE-2012-3570 An error in the handling of malformed client identifiers can cause a DHCP server running affected versions (see Impact) to enter a state where further client requests are not processed and the server process loops endlessly, consuming all available CPU cycles. Under normal circumstances this condition should not be triggered, but a non-conforming or malicious client could deliberately trigger it in a vulnerable server. In order to exploit this condition an attacker must be able to send requests to the DHCP server (CVE-2012-3571 Two memory leaks have been found and fixed in ISC DHCP. Both are reproducible when running in DHCPv6 mode (with the -6 command-line argument.) The first leak is confirmed to only affect servers operating in DHCPv6 mode, but based on initial code analysis the second may theoretically affect DHCPv4 servers (though this has not been demonstrated.) (CVE-2012-3954). The updated packages have been upgraded to the latest version (4.2.4-P1) which is not affected by these issues. Affected: 2011. Solution: To upgrade automatically use MandrakeUpdate or urpmi. The verification of md5 checksums and GPG signatures is performed automatically for you. http://www.securityspace.com/smysecure/catid.html?in=MDVSA-2012:115 Risk factor : High
