Description Japheth Cleaver 2016-10-24 04:37:12 UTC

Please see Bug #1380464 - et seq, through Bug #1380468

c-ares was added to RHEL6 as documented in Bug #513673. The security fix referenced here (and version bump) was applied to EPEL5, EPEL7, and all Fedora versions, but not the standard c-ares package in RHEL6, as far as I can tell.

Product Security rated this as having Moderate security impact and currently does not plan to address this issue in RHEL products. Note that impact of this issue on RHEL is less severe than impact on ChromeOS.

While noted, this does lead to the strange result that it's fixed for EL5 and EL7 users, but not those on EL6.

Furthermore, mingw-c-ares was updated in EL6, but the main c-ares package wasn't. This could easily lead to confusion.


I understand the specific chain of reasoning for the EL6 package... But this is one of those cases where I'd ask that the team reconsider this, and either backport the patch or also perform the rebase here too.

Comment 4 Jakub Hrozek 2017-11-14 21:16:43 UTC

I'm sorry, but given that RHEL-6 in in Production Phase 3 and given the reasoning in comment #2, I'm closing this bug as WONTFIX.

I understand the reasoning in comment #3, but I'm afraid we cannot fix bugs with this severity at this point of RHEL-6 lifecycle.
