An anonymous reader writes "Researchers from the University of Arizona have released a study that takes a look at the security of ten popular package managers. They were able to show all ten were vulnerable to attacks from a mirror or man-in-the-middle that allow an attacker to (along with other things) crash the system or obtain root access. Furthermore, the researchers created a fictitious administrator and company name and were able to lease a server and get it listed as an official mirror for all the distributions they tried (Ubuntu, Debian, Fedora, CentOS, and OpenSUSE). This raised the question: What keeps you up at night, the thought of attacks on your package manager or previously discussed and patched vulnerability in DNS?" justin samuel (one of the Arizona researchers) also points out a synopsis on CERT's blog.
