Bug 249398 – sys-freebsd/freebsd-sources-6.3 arc4random improper entropy source (CVE-2008-5162)

• Status: RESOLVED FIXED
• Product: Gentoo Security

[Description Stefan Behte (RETIRED) 2008-11-30 15:45:26 UTC]

CVE-2008-5162 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-5162):
  The arc4random function in the kernel in FreeBSD 6.3 through 7.1 does
  not have a proper entropy source for a short time period immediately
  after boot, which makes it easier for attackers to predict the
  function's return values and conduct certain attacks against the GEOM
  framework and various network protocols, related to the Yarrow random
  number generator.

http://www.gentoo.org/security/en/vulnerability-policy.xml does not list BSD, still I thought it would be ok to let bsd know this. I looked at the code, seems 6.2 also needs the patch.

According to the Gentoo Linux Vulnerability Treatment Policy, we're not handling freebsd bugs, closing.

Sorry, I handled this wrong. It needs to be fixed, too, of course.

fixed now in sources-6.2-r5
