The information is already provided in the bugzilla I pointed you to:

https://bugzilla.redhat.com/1130239#c2

Upstream curl-7.29.0 does not contain the bug. It was introduced by backport
of upstream commit 0feeab78 (included in upstream curl-7.31.0) into Fedora 19.
RHEL-7 inherited it from Fedora 19 later on. It can be fixed by upstream
commit d529f388 (included in upstream curl-7.32.0).

Additionally, as Daniel pointed out, the bug is known to appear only if the
threaded resolver is used.

The bug is now fixed in Fedora 19, which was the only stable Fedora release
suffering from this bug. However, it has not yet been approved by Product
Management for inclusion in a RHEL-7 update.
