Date: Tue, 17 Feb 2015 23:22:12 -0700 From: Kurt Seifried <kseifried@...hat.com> To: "oss-security@...ts.openwall.com" <oss-security@...ts.openwall.com>, Assign a CVE Identifier <cve-assign@...re.org>, security@...ebsd.org Subject: FreeBSD: URGENT: RNG broken for last 4 months https://lists.freebsd.org/pipermail/freebsd-current/2015-February/054580.html If you are running a current kernel r273872 or later, please upgrade your kernel to r278907 or later immediately and regenerate keys. I discovered an issue where the new framework code was not calling randomdev_init_reader, which means that read_random(9) was not returning good random data. read_random(9) is used by arc4random(9) which is the primary method that arc4random(3) is seeded from. This means most/all keys generated may be predictable and must be regenerated. This includes, but not limited to, ssh keys and keys generated by openssl. This is purely a kernel issue, and a simple kernel upgrade w/ the patch is sufficient to fix the issue. -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not." ======= I assume this needs a CVE, I know technically it didn't involve a release but quite a few people run -current (and it's a 4 month affected window), so if we're assigning CVE's to stuff hosted in github, then it seems fair that this should get one. -- Kurt Seifried -- Red Hat -- Product Security -- Cloud PGP A90B F995 7350 148F 66BF 7554 160D 4553 5E26 7993 Download attachment "signature.asc" of type "application/pgp-signature" (820 bytes)
