I reported this to the maintainer of Portage in Gentoo Bug #469888
[1], and it was fixed in commit b5969af9f5 [2].

Do note that while this commit solves the immediate problem with
fetching /Packages, as detailed above, there may be other additional
unconfirmed insecure uses of the vulnerable urlopen() function that
have not yet been analyzed or fixed.

emerge --sync uses plain rsync without any integrity verification. One
should worry about /Packages not before he started obtaining portage
tree using emerge-webrsync together with the webrsync-gpg feature
instead of emerge --sync.
