critical Nessus Plugin ID 60615
Language:
Synopsis
The remote Scientific Linux host is missing one or more security updates.Description
The Mandriva Linux Engineering Team discovered a stack-based buffer overflow flaw in the ISC DHCP client. If the DHCP client were to receive a malicious DHCP response, it could crash or execute arbitrary code with the permissions of the client (root). (CVE-2009-0692)An insecure temporary file use flaw was discovered in the DHCP daemon's init script ('/etc/init.d/dhcpd'). A local attacker could use this flaw to overwrite an arbitrary file with the output of the 'dhcpd
-t' command via a symbolic link attack, if a system administrator executed the DHCP init script with the 'configtest', 'restart', or 'reload' option. (CVE-2009-1893)
Solution
Update the affected dhclient, dhcp and / or dhcp-devel packages.See Also
