For the non-geekified: this is the stuff required for &#8220;secure&#8221; web sites to stay secure, and what people typically use to log into systems remotely without their passwords being freely scattered for any hacker to see and exploit.<\/p>\n<p>The problem?  The encryption keys used to keep your logins safe and private hinge around <a href=\"http:\/\/en.wikipedia.org\/wiki\/Pseudorandom_number_generator\">seemingly-random numbers<\/a> that the system must generate.  However, sometime in September 2006, a developer got a bit careless and made a revision to the software that suddenly made the random number generator, well, not-so-random.  The result?  The encryption keys are theoretically easy to guess and decrypt, leaving those once-believed-private transactions very vulnerable and exposed. <\/p>\n<p>Here are the security notices from Debian (<a href=\"http:\/\/www.debian.org\/security\/2008\/dsa-1571\">here<\/a> and <a href=\"http:\/\/www.debian.org\/security\/key-rollover\/\">here<\/a>), and Ubuntu (<a href=\"http:\/\/www.ubuntu.com\/usn\/usn-612-1\">here<\/a>, <a href=\"http:\/\/www.ubuntu.com\/usn\/usn-612-2\">here<\/a> and <a href=\"http:\/\/www.ubuntu.com\/usn\/usn-612-3\">here<\/a>), the two biggest Linux flavors affected by this security hole.  The notices include fixes, and updates are available, but sysadmins <strong>need<\/strong> to follow the instructions to make the fix effective.<\/p>\n<p>Of course, there&#8217;s are those aforementioned <a href=\"http:\/\/en.wikipedia.org\/wiki\/List_of_Linux_distributions#Debian-based\">40+ other known derivatives<\/a> of these two major Linux distributions that are probably affected, too.<\/p>\n<p>And here&#8217;s a statement I never really thought I&#8217;d find myself saying: if you use Windows, you have nothing to worry about, because all of this means nothing to you.<\/p>\n<p>P.S.: Yes, this server has been patched. \ud83d\ude42<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Well, seeing as lately my blog is geeking-out over Ubuntu, I may as well add this posting to the list, and it&#8217;s a doozy.<\/p>\n","protected":false},"author":6,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4],"tags":[58,59,60,57],"class_list":["post-676","post","type-post","status-publish","format-standard","hentry","category-gadgets-widgits-and-whatzits","tag-debian","tag-linux","tag-security","tag-ubuntu"],"_links":{"self":[{"href":"https:\/\/scaredpoet.com\/blog\/index.php?rest_route=\/wp\/v2\/posts\/676","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/scaredpoet.com\/blog\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/scaredpoet.com\/blog\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/scaredpoet.com\/blog\/index.php?rest_route=\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/scaredpoet.com\/blog\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=676"}],"version-history":[{"count":0,"href":"https:\/\/scaredpoet.com\/blog\/index.php?rest_route=\/wp\/v2\/posts\/676\/revisions"}],"wp:attachment":[{"href":"https:\/\/scaredpoet.com\/blog\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=676"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/scaredpoet.com\/blog\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=676"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/scaredpoet.com\/blog\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=676"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
