You are being emailed as the upstream contact. Please keep oss-security@...ts.openwall.com CC'd for any updates on this issue. This issue should be considered public. A CVE is being requested; please mention this in any changelogs. Details from the public bug follow: https://launchpad.net/bugs/804594 From the reporter: "reseed(8) performs an insecure HTTP fetch of data from random.org. The script is automatically executed when installed, and any time the user chooses to execute. In addition, the reseed man pages do not mention the data is retrieved over an insecure channel." As pointed out by the reporter, from the man page: "It is run once during the installation of the package only". An attacker could perform a MITM during package installation or whenever the reseed command is run to provide predictable data for the random number seed.
