Description Hans de Graaff gentoo-dev 2017-08-28 18:55:25 UTC
Fix a DNS request hijacking vulnerability. Fix by Samuel Giddins.
Fix an ANSI escape sequence vulnerability. Fix by Evan Phoenix.
Fix a DOS vulernerability in the query command. Fix by Samuel Giddins.
Fix a vulnerability in the gem installer that allowed a malicious gem to overwrite arbitrary files. Fix by Samuel Giddins.

dev-ruby/rubygems-2.6.13 has been added to the repository. Because this is such a central ruby package I'd like to wait a week for bugs to shake out before moving to stable.

In terms of overall impact: we don't use rubygems to install any packages within Gentoo itself so normal Gentoo operation is not affected, but users with an interest in ruby are expected to run rubygems in a way that may trigger these vulnerabilities.

@security: are we going to wait for arm64? Haven't seen any activity by them for some time and they are not security supported, correct? Otherwise we are ready for cleanup and we can proceed with this bug.

ATM no one seems to be working on arm64... I tried to contact them, no answer.
Security bugs must proceed since all supported arches are stable now.

@arm64 please try to stabilize before cleanup, if you can't you'll need to open a new stabilization request.

@Hans proceed to cleanup.

New GLSA Request filed.
