Dear Security Team, I have prepared a new upload addressing a number of open security issues in Xen. Due to the complexity of the patches that address XSA-273 [0] the packages have been built from upstream's staging-4.8 / staging-4.10 branch again as recommended in that advisory. Commits on those branches are restricted to those that address the following XSAs (cf. [1]): - XSA-273 (CVE-2018-3620, CVE-2018-3646) - XSA-272 (no CVE yet) - XSA-269 (...

In the end, it was effectively decided that these patches were not recommended until they were reviewed again and XSA-289 has no official list of flaws or fixes as a result....

...security updates. This is a SIG that requires community participation .. so far, George Dunlap and I are really the only people contributing. This is volunteer work for both of us. We could stand some more volunteers. In any event, the updates we release come from here: https://xenbits.xen.org/xsa/ When they release an XSA, we incorporate it and do a new release. Support for older releases will be done (currently by only me .. volunteers welcome) based on this schedule: https://wiki.xenproject.org/wiki/Xen_Project_Release_Features So, we will support 4.4 on CentOS-6 until 'March 2017...
