Categoría:	Mandrake Local Security Checks
Título:	Mandrake Security Advisory MDKSA-2004:061 (dhcp)
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing an update to dhcp announced via advisory MDKSA-2004:061. A vulnerability in how ISC's DHCPD handles syslog messages can allow a malicious attacker with the ability to send special packets to the DHCPD listening port to crash the daemon, causing a Denial of Service. It is also possible that they may be able to execute arbitrary code on the vulnerable server with the permissions of the user running DHCPD, which is usually root. A similar vulnerability also exists in the way ISC's DHCPD makes use of the vsnprintf() function on system that do not support vsnprintf(). This vulnerability could also be used to execute arbitrary code and/or perform a DoS attack. The vsnprintf() statements that have this problem are defined after the vulnerable code noted above, which would trigger the previous problem rather than this one. Thanks to Gregory Duchemin and Solar Designer for discovering these flaws. The updated packages contain 3.0.1rc14 which is not vulnerable to these problems. Only ISC DHCPD 3.0.1rc12 and 3.0.1rc13 are vulnerable to these issues. Affected versions: 10.0, 9.2 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=MDKSA-2004:061 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-0460 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-0461 http://www.kb.cert.org/vuls/id/317350 http://www.kb.cert.org/vuls/id/654390 Risk factor : Critical CVSS Score: 10.0
