isc-dhcp-server -- DoS in DHCPv6

ISC reports: Due to improper handling of a DHCPv6 lease structure, ISC DHCP servers that are serving IPv6 address pools AND using Dynamic DNS can encounter a segmentation fault error while updating lease status under certain conditions. The potential exists for this condition to be intentionally...

SuSE 11.1 Security Update : dhcpcd (SAT Patch Number 4389)

A rogue DHCP server could instruct clients to use a host name that contains shell meta characters. Since many scripts in the system do not expect unusal characters in the system's host name the DHCP client needs to sanitize the host name offered by the server. CVE-2011-0996 Note this update is...

BBC botnet buy: What were they thinking?

By Roel Schouwenberg As Dancho Danchev pointed out, the BBC leased itself a botnet zdnet.com. I couldn’t quite believe it when I read it. The BBC, arguably one of the very best TV producers in the world, surely should have known better? There are so many things wrong about this that I hardly know...
