HP patches 'bricking' bug in software update service
Hewlett-Packard Co. has fixed flaws in a patch-management program
bundled with its computers, printers and other hardware that could be
used by hackers to "brick" HP or Compaq PCs.
In an alert sent to customers who subscribe to its security warning
service, HP said users should run Software Update to patch the flaws disclosed last week by a Polish researcher known only by his alias, "porkythepig." A pair of bugs in the update service's ActiveX
control can be used to execute remote code or gain additional access
rights, porkythepig said then. He also posted proof-of-concept exploit
code that showed how to use one of the vulnerabilities to overwrite and
corrupt crucial Windows' system files, an attack that would leave any
affected PC unbootable.
