This version: python-2.3.3.ebuild:KEYWORDS="x86 ppc sparc hppa amd64 s390 alpha ia64 ppc64" is not affected and is pretty much stable on * (heck, even s390). Vulnerability can be found here with many a reference: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0150 Debian and Mandrake already have security announcements out. I believe we should have one too (considering how extensively used python is on gentoo..).
Changing whiteboard, accepting bug.
