UEFI Secure Boot Booted From Debian 9 'Stretch'
by Peter Reutemann 02 May '17

02 May '17

'In a release update from last week, release team member Jonathan Wiltshire wrote that "At a recent team meeting, we decided that support for Secure Boot in the forthcoming Debian 9 'stretch' would no longer be a blocker to release. The likely, although not certain outcome is that stretch will not have Secure Boot support." "We appreciate that this will be a disappointment to many users and developers," he continued, "However, we need to balance that with the limited time available for the volunteer teams working on this feature, and the risk of bugs being introduced through rushed development." The decision not to offer Secure Boot support at release leaves Debian behind Red Hat and Suse, making it the only one of Linux's three main branches not to support the heir-to-BIOS and the many security enhancements it offers.' -- source: https://linux.slashdot.org/story/17/05/01/1452209 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel Patches Remote Execution Hole That's Been Hidden In Its Chips Since 2008
by Peter Reutemann 02 May '17

02 May '17

'Intel processor chipsets have, for roughly the past nine years, harbored a security flaw that can be exploited to remotely control and infect vulnerable systems with virtually undetectable spyware and other malicious code. Specifically, the bug is in Intel's Active Management Technology (AMT), Standard Manageability (ISM) and Small Business Technology (SBT) firmware versions 6 to 11.6. According to Chipzilla, the security hole allows "an unprivileged attacker to gain control of the manageability features provided by these products." That means hackers exploiting the flaw can silently snoop on a vulnerable machine's users, make changes to files and read them, install rootkits and other malware, and so on. This is possible across the network, or with local access. These management features have been available in various Intel chipsets for years, starting with the Nehalem Core i7 in 2008, all the way up to Kaby Lake Core parts in 2017. According to Intel today, this critical security vulnerability, labeled CVE-2017-5689, was found and reported in March by Maksim Malyutin at Embedi. To get the patch to close the hole, you'll have to pester your machine's manufacturer for a firmware update, or try the mitigations here. These updates are hoped to arrive within the next few weeks.' -- source: https://hardware.slashdot.org/story/17/05/01/228211 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
