Categoría:	Mandrake Local Security Checks
Título:	Mandriva Security Advisory MDVSA-2012:116 (dhcp)
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing an update to dhcp announced via advisory MDVSA-2012:116. Multiple vulnerabilities has been discovered and corrected in ISC DHCP: 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 patched to correct these issues. Affected: Enterprise Server 5.0 Solution: To upgrade automatically use MandrakeUpdate or urpmi. The verification of md5 checksums and GPG signatures is performed automatically for you. https://secure1.securityspace.com/smysecure/catid.html?in=MDVSA-2012:116 Risk factor : High
