• Status: RESOLVED FIXED
• Product: Gentoo Security

[Description Robert Buchholz (RETIRED) 2008-01-04 22:28:11 UTC]

CVE-2007-6590 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2007-6590):
  Mozilla 1.9 M8 and earlier, Mozilla Firefox 2, SeaMonkey 1.1.5, Netscape 9.0,
  and other Mozilla-based web browsers, when a user accepts an SSL server
  certificate on the basis of the CN domain name in the DN field, regard the
  certificate as also accepted for all domain names in subjectAltName:dNSName
  fields, which makes it easier for remote attackers to trick a user into
  accepting an invalid certificate for a spoofed web site.
